13.5.2.4 Input Capture (IC) Mode
MC68F375
REFERENCE MANUAL
sequence of events is repeated for each subsequent capture. Reading data register B
returns the value in register B2.
If a 32-bit coherent operation is in progress when an edge is detected, the transfer of
data from B1 to B2 is deferred until the coherent operation is completed. At any time,
the input level present on the input pin can be read on the IN bit.
The input pulse period is calculated by subtracting the value in data register B from the
value in data register A.

measurement.
IC mode is selected by making MODE[3:0] = 0011.
This mode is identical to the input period measurement mode (IPM) described above,
with the exception that the FLAG bit is also set at the occurrence of the first detected
edge of the selected polarity. In this mode the DASM functions as a standard input
capture function in a similar way to the M68HC11 family timers. In this case the value
latched in channel B can be ignored.
