Force B. 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.These bits are used to select which of the four possible 16-bit counter bus passing
nearby is used by the MDASM. Refer to
the 16-bit counter buses in the MIOS1.
NOTE: In the MPC555 / MPC556, only 0b00 (CB6) and 0b01 (CB22) are implemented.
0
Mode select. These 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. It is also imperative to go through the disable mode before changing the oper-
ating mode. See
