IR Receive
When configured in receive mode (IRMODE = 0), the IR
hardware supports the IRRX capture function. The
IRRXSEL[1:0] bits define which edge(s) of the IRRX pin
should trigger IR timer capture function.
The IR module starts operating in the receive mode
when IRMODE = 0 and IREN = 1. Once started, the IR
timer (IRV) starts up counting from 0000h when a quali-
fied capture event as defined by IRRXSEL happens.
The IRV register is, by default, counting carrier cycles
as defined by the IRCA register. However, the IR carrier
frequency detect (IRCFME) bit can be set to 1 to allow
clocking of the IRV register directly with the IRCLK for
finer resolution. When IRCFME = 0, the IRCA defined
carrier is counted by IRV. When IRCFME = 1, the
IRCLK clocks the IRV register.
