11.6 IR Capture Control (
IRCC
)
11.6.1 Overview
MC96FR116C has an IR capture module which receives and captures the incoming digital IR signal
to detect the IR carrier frequency and count the carrier number. With this module, the Watch Timer
and Timer 2 can be configured to operate in IR capture mode by setting IRCEN bit in IRCC1 register.
Also Timer 3 can support IR capture feature. Both Timer 2 and Timer 3 can detect the envelop of
incoming carrier or count the number of input carrier signal according to the setting of IRCC2 register.
