The HC12 Enhanced Capture Timer module has the features of the
HC12 Standard Timer module enhanced by additional features in order
to enlarge the field of applications, in particular for automotive ABS
applications.
The additional features permit the operation of this timer module in a
mode similar to the Input Control Timer implemented on
MC68HC11NB4.
These additional features are:
•
•
•
•
•
16-Bit Buffer Register for four Input Capture (IC) channels.
Four 8-Bit Pulse Accumulators with 8-bit buffer registers
associated with the four buffered IC channels. Configurable also
as two 16-Bit Pulse Accumulators.
16-Bit Modulus Down-Counter with 4-bit Prescaler.
Four user selectable Delay Counters for input noise immunity
increase.
Main Timer Prescaler extended to 7-bit.
