15.3 Enhanced Capture Timer Modes of Operation
The Enhanced Capture Timer has 8 Input Capture, Output Compare
(IC/OC) channels same as on the HC12 standard timer (timer channels
TC0 to TC7). When channels are selected as input capture by selecting
the IOSx bit in TIOS register, they are called Input Capture (IC)
channels.
