Force B bit — In the OCB, OCAB and OPWM modes, the FORCB bit allows the software to force
the output flip-flop to behave as if a successful comparison had occurred on channel B (except
that the FLAG line is not activated). Writing a one to FORCB resets the output flip-flop; writing a
zero to it 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 is always read as zero.
Writing a one to both FORCA and FORCB simultaneously resets the output flip-flop.
Reserved
Bus select bits — These bits are used to select which of the six 16-bit counter buses is used by
the MDASM. Each MDASM instance has four possible counter buses that may be connected.
See
NOTE: Unconnected counter buses inputs are grounded.
Reserved
Mode select bits — The four mode select bits select the mode of operation of the MDASM. To
avoid spurious interrupts, it is recommended that MDASM interrupts are disabled before
changing the operating mode.
The mode select bits are cleared by reset.
NOTE: The reserved modes should not be set; if these modes are set, the MDASM behavior is
undefined.
