MOTOR CONTROLLER (Cont’d)
REPETITION COUNTER REGISTER (MREP)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:0 = REP[7:0] Repetition counter value (N).
This register allows the user to set-up the update
rate of the PWM counter compare register (i.e. pe-
riodic transfers from preload to active registers),
as well as the PWM Update interrupt generation
rate, if these interrupts are enabled.
Each time the MREP related Down-Counter
reaches zero, the Compare registers are updated,
a U interrupt is generated and it re-starts counting
from the MREP value.
After a microcontroller reset, setting the CKE bit in
the MCRA register (i.e. enabling the clock for the
MTC peripheral) forces the transfer from the
MREP preload register to its active register and
generates a U interrupt. During run-time (while
CKE bit = 1) a new value entered in the MREP
preload register is taken into account after a U
event.
