Static Level during Active Phase:
When bit ESMC in SFR CMSEL1 is set, static active or passive output levels during the
active phase of a multi-phase PWM timing are generated when the following conditions
are met:
– The 16-bit offset register of Compare Timer 1 must be 0000_H
(CT1OFH = CT1OFL = 00_H)
– static active:
compare values = 0000_H
static passive: compare values > period value
– The bits CMSELx3 (x = 0-2) in the SFRs CMSEL0/CMSEL1 must be 0.
The logic state of the inactive/active phases at the CCx and COUTx outputs is defined
by the bits in SFR COINI.
