Enhanced Capture Timer (ECT16B8CV3)
14.1
The HCS12 enhanced capture timer module has the features of the HCS12 standard timer module
enhanced by additional features in order to enlarge the field of applications, in particular for automotive
ABS applications.
This design specification describes the standard timer as well as the additional features.
The basic timer consists of a 16-bit, software-programmable counter driven by a prescaler. This timer can
be used for many purposes, including input waveform measurements while simultaneously generating an
output waveform. Pulse widths can vary from microseconds to many seconds.
A full access for the counter registers or the input capture/output compare registers will take place in one
clock cycle. Accessing high byte and low byte separately for all of these registers will not yield the same
result as accessing them in one word.
