Modular Input/Output Subsystem (MIOS14)
If a 32-bit coherent operation is in progress when an edge (except for the first 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 signal can be read on the PIN bit.
The input pulse period is calculated by subtracting the value in data register B from the value in data
register A.

IC mode is selected by setting MODE[0:3] to 0b0011.
This mode is identical to the input period measurement mode (IPM) described above, with the exception
that the FLAG line is also activated at the occurrence of the first detected edge of the selected polarity. In
this mode the MDASM functions as a standard input capture function. In this case the value latched in
channel B can be ignored.
