Motor Controller Period Register
The period register defines PER, the number of motor controller timer counter clocks a PWM period lasts.
The motor controller timer counter is clocked with the frequency f
TC
. If dither mode is enabled (DITH = 1,
refer to
Section 16.4.1.3.5, “Dither Bit (DITH)”
), P0 is ignored and reads as a 0. In this case
PER = 2 * D[10:1].
For example, programming MCPER to 0x0022 (PER = 34 decimal) will result in 34 counts for each
complete PWM period. Setting MCPER to 0 will shut off all PWM channels as if MCAM[1:0] is set to 0
in all channel control registers after the next period timer counter overflow. In this case, the motor
controller releases all pins.
NOTE
Programming MCPER to 0x0001 and setting the DITH bit will be managed
as if MCPER is programmed to 0x0000. All PWM channels will be shut off
after the next period timer counter overflow.
