Program loop constructs, free from loop count management overhead, are supported using the DO and REPEAT instructions, both of which are interruptible at any point. Timers 5×16 bit timers The QEI module provides the interface to incremental encoders for obtaining mechanical position data. The duty cycle registers are bits wide. Occurrence of multiple trap conditions simultaneously will cause a Reset. Auth with social network: A third channel, termed index pulse, occurs once per revolution and is used as a reference to establish an absolute position.
About project SlidePlayer Terms of Service. Share buttons are a little bit lower.
Ehsan Shams Saeed Sharifi Tehrani. Attempted execution of any unused opcodes will result in an illegal instruction trap. The timer will begin counting downwards on the following input clock edge.
mikropascal – MikroElektronika
Similar operation but single shot. If Phase A leads Phase B, then the direction of the motor is deemed positive or forward. The data space is 64 Kbytes 32K words and is split into two blocks, referred to as X and Y data memory. 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.

There are two methods by which program space can be accessed; via special table instructions, or through the remapping of a 16K word program space page into the upper half of data space. The index pulse coincides with Phase A and Phase B, both low. However, as the architecture is modified Harvard, data can also be present in program space.
TxPx, Timer x Period. The SA or SB bit is set and remains set until cleared by the user.
This is primarily intended to remove the loop overhead for DSP algorithms. If a peripheral is enabled, but the peripheral is not actively driving a pin, that pin may be driven by a port.
The working register array consists of 16xbit registers, each of which can act as data, address or offset registers. Most instructions operate solely through the X memory, AGU, which provides the appearance of a single, unified ocurs space.
My presentations Profile Feedback Log out. When bit couurs overflow and saturation occurs, the saturation logic loads the maximally positive 9. For most instructions, the core is capable of executing a data or program data memory read, a working register data read, a data memory write and a program instruction memory read per instruction cycle.
We think you have liked this presentation. Consequently, instructions are always aligned. No saturation operation is performed and the accumulator is allowed to overflow destroying its sign. The PWM outputs use push-pull drive circuits. A consequence of this algorithm is that over a succession of random rounding operations. To make this website work, we log user data and share it with processors. Conventional or convergent rounding RND.

ACCB overflowed into guard bits 3.
The DSP engine also has the capability to perform inherent accumulator-to-accumulator operations which require no additional data.
