DASMB is the data register associated with channel B. Table 64 shows how DASMB is used with the
different operating modes. Depending on the mode selected, software access is to register B1 or reg-
ister B2.
Table 63 DASMA Operations
Mode
DASMA Operation
DIS
DASMA can be accessed to prepare a value for a subsequent mode selection
IPWM
DASMA contains the captured value corresponding to the trailing edge of the measured pulse
IPM
DASMA contains the captured value corresponding to the most recently detected user-specified
rising or falling edge
IC
DASMA contains the captured value corresponding to the most recently detected user-specified
rising or falling edge
OCB
DASMA is loaded with the value corresponding to the leading edge of the pulse to be generated.
Writing to DASMA in the OCB and OCAB modes also enables the corresponding channel A com-
parator until the next successful comparison.
OCAB
DASMA is loaded with the value corresponding to the leading edge of the pulse to be generated.
Writing to DASMA in the OCB and OCAB modes also enables the corresponding channel A com-
parator until the next successful comparison.
OPWM
DASMA is loaded with the value corresponding to the leading edge of the PWM pulse to be gen-
erated.
