DASMB is the data register associated with channel B. Table D-48 shows how
DASMB is used with the different modes of operation. Depending on the mode select-
ed, software access is to register B1 or register B2.

DASMA can be accessed to prepare a value for a subsequent mode selection
DASMA contains the captured value corresponding to the trailing edge of the measured pulse
DASMA contains the captured value corresponding to the most recently detected user-specified rising
or falling edge
DASMA contains the captured value corresponding to the most recently detected user-specified rising
or falling edge
DASMA is loaded with the value corresponding to the leading edge of the pulse to be generated. Writ-
ing to DASMA in the OCB and OCAB modes also enables the corresponding channel A comparator
until the next successful comparison.
