Uninitialized W Register Trap: About project SlidePlayer Terms of Service. Ehsan Shams Saeed Sharifi Tehrani. We think you have liked this presentation.

ACCA overflowed into guard bits 2. Thus, the PWM resolution is effectively doubled. The data space is 64 Kbytes 32K words and is split into two blocks, referred to as X and Y data memory.

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. Convergent or unbiased rounding operates in the same manner as conventional rounding, except when ACCxL equals 0x A third channel, termed index pulse, occurs once per revolution and is used as a reference to establish an absolute position.

When bit 31 overflow and saturation occurs, the saturation logic then dspc the maximally positive 1. For input courw greater than 0xFFF, data written to memory is forced to the maximum positive 1. If Xours A leads Phase B, then the direction of the motor is deemed positive or forward. The output of the sample and hold is the input into the converter which generates the result. The timer counts up to a match value preloaded in PR1, then resets to 0 and continues.


For input data less than 0xFF, data written to memory is forced to the maximum negative 1. In the bit Asynchronous Counter mode, the timer increments on every rising edge of the applied external clock signal. Bit 31 Overflow and Saturation: Reads from the latch LATxread the latch.

A total of 12 TAD cycles cors required to perform the complete conversion.

Similar operation but single shot. 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. To make this website work, we log user data and share it with processors. Coirs Forgot your password? If Phase A lags Phase B, then the direction of the motor is deemed negative or reverse.

Most instructions operate solely through the X memory, AGU, which provides the appearance of a single, unified data space. The watchdog has timed out, indicating that the processor is no longer executing the correct flow of code. The working register array consists of 16xbit registers, each coure which can act as data, address or offset registers. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port.

Share buttons are a little bit lower.

Input capture is useful for such modes as: In particular, the following power and motion control applications are supported by the PWM module: Timers 5×16 bit timers The QEI module provides the interface to incremental encoders for obtaining mechanical position data.


Phase A, Phase B and an index pulse. A momentary dip in the power supply to the device has been detected which may result in malfunction. Assuming that bit 16 is effectively random in nature, this scheme removes any rounding bias that may accumulate. Auth with social network: The bit timer has the ability to generate an interrupt on period match. In the Dwpic Time Accumulation mode, the timer clock source is derived from the internal system clock.

One working register W15 operates as a software Stack Pointer for interrupts dzpic calls. Published by Candace Morgan Modified over 3 years ago.

However, as the architecture is modified Harvard, data can also be present in program space.


The ADC module has 16 analog inputs which are multiplexed into four sample and hold amplifiers. Conventional or convergent rounding RND. This is primarily intended to remove the loop overhead for DSP algorithms.

TxPx, Timer x Period.

Data accesses to this area add an additional cycle to the instruction being executed, since two program memory fetches are required.
