If Phase A lags Phase B, then the direction of the motor is deemed negative or reverse. Data accesses to this area add an additional cycle to the instruction dsic executed, since two program memory fetches are required. Input capture is useful for such modes as: In the bit Timer mode, the timer increments on every instruction cycle up to a match value, preloaded into the Period register, PR1, then resets to 0 and continues to count.

No saturation operation is performed and the accumulator is allowed to overflow destroying its sign. ACCA overflowed into guard bits 2. Feedback Privacy Policy Feedback. Uninitialized W Register Trap: Writes to the latch, write the latch LATx. System block diagram A8 version. The ADC module has a unique feature of being able to operate while the device is in Sleep mode.

The bit, high-speed Analog-to-Digital Converter ADC allows conversion of an analog input signal to a bit digital number. The source can be either of the two DSP accumulators or the X bus to support multi-bit shifts of register or memory data. In particular, the following power and motion control applications are supported by the PWM module: An attempt to use an uninitialized W register as an Address Pointer will cause a Reset. This allows program memory addresses to directly map to data space addresses.

When bit 39 overflow and saturation occurs, the saturation logic loads the maximally positive 9. The PWM outputs use push-pull drive circuits. Most instructions operate solely through the X memory, AGU, which provides the appearance of a single, unified data space.

All port pins are defined as inputs after a Reset. In the bit Synchronous Counter mode, the timer increments on the rising edge of the applied external clock signal, which is synchronized with the internal phase clocks. For input data less than 0xFF, data written to memory is forced to the maximum negative 1.

The ADC module has 16 analog inputs which are multiplexed into four sample and hold amplifiers.

Due to the inability of the power output devices to switch instantaneously, some amount of time must be provided between the turn-off event of one PWM output in a complementary pair and the turn-on event of the other transistor. We think you have liked this presentation.

Bit 39 Catastrophic Overflow The bit 39 overflow Status bit from the adder is used to set the SA or SB bit, which remain set until cleared by the user. TxPx, Timer x Period. The SA or SB bit is set and remains set until cleared by the user.

One working register W15 operates as a software Stack Pointer for interrupts and calls. Consequently, instructions are always aligned. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port. The timer counts up to a match value preloaded in PR1, then resets to 0 and continues.

If Phase A leads Phase B, then the direction of the motor is deemed positive or forward. The working register array consists of corus registers, each of which can act as data, address or offset registers.

Attempted execution of any unused opcodes will result in an illegal instruction trap. The OCxR register is compared against the incrementing timer count, TMRy, and the leading rising edge of the pulse is generated at the OCx pin, on corus compare match event. Program memory can thus be regarded as two, bit word-wide address spaces, residing side by side, each with the same address range. In the bit Asynchronous Counter mode, the timer increments on every rising edge of the applied external clock signal.

For input data greater than 0xFFF, data written to dsplc is forced to the maximum positive 1. Assuming that bit 16 is effectively random in nature, this scheme removes any rounding bias that may accumulate.

Ramadan Al-Azhar University Lecture 3. Ehsan Shams Saeed Sharifi Tehrani. When a peripheral is enabled and the peripheral is actively driving an associated pin, the use of the pin as a general purpose output pin is disabled. The data space is 64 Kbytes 32K words and is split into two blocks, referred to as X and Y data memory. The watchdog has timed out, indicating that the processor is no longer executing the correct flow of code.

My presentations Profile Feedback Log out. To make this website work, we log user data and share it with processors.

The OCxRS register is then compared to the same incrementing timer count, TMRy, and the trailing falling edge of the pulse is generated at the OCx pin, on a compare match event. A consequence of this algorithm is that over a succession of random rounding operations.

This is primarily intended to remove the loop overhead for DSP algorithms. Published by Candace Morgan Modified over 3 years ago. Timers 5×16 bit timers The QEI module provides the interface to incremental encoders for obtaining cpurs position data. Bit 31 Overflow and Saturation: The output of the sample and hold is the input into the converter which generates the result.
