REFERENCE MANUAL
When using 16 bits of resolution on the comparator (MODE[2:0] = 000), the output can
vary from a 0% duty cycle up to a duty cycle of 65535/65536. In this case it is not pos-
sible to have a 100% duty cycle. In cases where 16-bit resolution is not needed, it is
possible to have a duty cycle ranging from 0% to 100%. Setting bit 15 of the value
stored in register B to ‘1’ results in the output being ‘always set’. Clearing bit 15 (to ‘0’)
allows normal comparisons to occur and the normal output waveform is obtained.
Changes to and from the 100% duty cycle are done synchronously, as are all other
width changes.
In the OPWM mode, the WOR bit selects whether the output is totem pole driven or
open-drain.
When the FLAG bit is set, an interrupt request is generated on one of eight levels as
defined by the interrupt level bits (IL[2:0]) in the DASMSIC register. If the interrupt level
is set to zero, interrupts are disabled.
When the IMB FREEZE signal is recognized, the DASM capture and compare func-
tions are halted. As soon as the FREEZE signal is negated, DASM actions resume as
if nothing had happened. During freeze, the IN bit of the DASMSIC register is readable
