10 16-bit Multi-purpose Timers (MPTs)
(1) Setting the PWM period
(2) Compare function
Comparator input is updated at every PWM period. It is also possible to update comparator input at
every half PWM period.
(MTPDnCMPU, MTPDnCMPV, MTPDnCMPW) and the carrier wave generated by the PWM counter
(MTPDnMDCNT) to determine which is larger to generate PWM waveforms with the desired duty.
compare register value is loaded at every PWM period (when the internal counter value matches the
MTPDnMDPRD value). It is also possible to update the compare register at every 0.5 PWM periods.
The PWM period is determined by the MTPDnMDPRD register. This register is double-buffered.
The pulse width modulation circuit compares the PWM compare registers of the 3 phases
The PWM compare register of each phase has a double-buffered compare register. The PWM
