D.7 New Input Capture/Transition Counter (NITC)
Any channel of the TPU can capture the value of a specified TCR or any specified lo-
cation in parameter RAM upon the occurrence of each transition or specified number
of transitions, and then generate an interrupt request to notify the bus master. The
times of the most recent two transitions are maintained in parameter RAM. A channel
can perform input captures continually, or a channel can detect a single transition or
specified number of transitions, ceasing channel activity until reinitialization. After
each transition or specified number of transitions, the channel can generate a link to
other channels. See Motorola TPU Progamming Note
