8.6
The MC1323x has four independent timer/PWM modules, each with one channel. Each TPM module is
based on a 16-bit counter and provides input capture, output compare, and pulse width modulation. Each
TPM module has one associated I/O pin for input capture or counter/PWM output.
TPM module features include:
8.7
The MC1323x carrier modulator timer module is intended as an IR LED driver for remote control “blaster”
applications. The module consists of a carrier generator, modulator, and transmitter that drives data to the
output (IRO) pin either in baseband or in FSK mode. The IRO pin drives (modulates) the IR diode directly
or through a buffer depending on the required current. The IRO pin is specified for 20mA drive.
The CMT module features include:
