Repetition counter value (N)
This register allows the user to set up the update rate of the PWM counter compare
register (that is, periodic 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 (that is,
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.
