USER’S MANUAL
In the OCB, OCAB and OPWM modes, FORCA bit allows software to force the output
flip-flop to behave as if a successful comparison had occurred on channel A (except
that the FLAG bit is not set). Writing a one to FORCA sets the output flip-flop; writing
a zero has no effect.
In the DIS, IPWM, IPM and IC modes, the FORCA bit is not used and writing to it has
no effect.
FORCA is cleared by reset, and always reads as zero.
In the OCB, OCAB and OPWM modes, FORCB allows software to force the output flip-
flop to behave as if a successful comparison had occurred on channel B (except that
the FLAG bit is not set). Writing a one to FORCB sets the output flip-flop, writing a zero
has no effect.
In the DIS, IPWM, IPM and IC modes, the FORCB bit is not used and writing to it has
no effect.
FORCB is cleared by reset, and always reads as zero.
EDPOL selects different options depending on the DASM operating mode. Refer to
Table D-45.
OCB, OCAB, OPWM
IPM, IC
Writing a one to both FORCA and FORCB simultaneously resets the
output flip-flop.
Writing a one to both FORCA and FORCB simultaneously resets the
output flip-flop.
