P42/CARR pin output
Carrier waveform
(Timer 2 output)
Software carrier wave output bit
Waveform output timing of remote-control waveform by software carrier waveform output bit
Set “1” to bit 1 to stop counting of timer 2.
Timer 1, 2, 3 control register TC123 (2B16)
Set “0” to bit 1 to start counting of timer 2.
Carrier wave control register, CARCNT (2716)
Timer 1, 2, 3 control register TC123 (2B16)
Set “1” to bit 1 to stop counting of timer 2.
Carrier wave control register, CARCNT (2716)
Timer count source set register TCSS (2A16)
Set timer 2 count source to bit 0 and bit 1. Also, in order to initialize
carrier waveform circuit, be sure to select f(XIN)/16, f(XIN)/2 or f(XIN)/8
for timer 3 count source.
Do not select carrier waveform output (b3b2=112) for timer 3 count source.
Carrier wave control register, CARCNT (2716)
Timer 2 secondary T2S (2D16)
Timer 2 primary T2P (2C16)
Set carrier wave “H”, “L” duration to timer 2 primary and timer 2 secondary, respectively.
(when 455 kHz carrier waveform generating mode is used,
this setting is not necessary.)
Waveform output of remote-control
Start (initial state after reset)
Timer 1, 2, 3 control register TC123 (2B16)
Generating waveform or not can be controlled by
bit 2: Software carrier waveform output bit
In order to stop carrier waveform,
set bit 2: Software carrier waveform output bit to “0: Output invalid”.
X: Set it to “0” or “1” arbitrary.
When the carrier wave output circuit operation is started again,
execute the setting from the processing No.4 .
In order to change the carrier wave control from the auto-control by timer 3
to software carrier wave output, initialize the carrier wave circuit
by setting “0” to “bit 1: carrier wave output valid bit”.
Set carrier wave control register.
bit 0: Set whether to expand waveform.
bit 1: Select “1: Carrier waveform generating function is valid”
bit 2: Select “0: Software output is invalid”
bit 3: Select “0: auto-control by timer 3 is invalid.
bit 4: Select “0: carrier waveform output trigger is invalid”
bit 5: Select whether 455 kHz carrier waveform generating mode is valid or invalid.
bit 6: Set output level of waveform.
bit 7: Set this bit to “0”.
