Setup Procedure
(6) Select the normal timer operation.
TM0MD (x'3F54')
bp4 : TM0PWM = 0
bp5 : TM0MOD = 0
(7) Select the count clock source.
TM0MD (x'3F54')
bp2-0 : TM0CK2-0 = 000
(8) Set the base cycle of remote control
carrier.
TM0OC (x'3F52')
(9) Start the timer operation.
TM0MD (x'3F54')
bp3 : TM0EN
(10) Enable the remote control carrier
output.
RMCTR (x'3F6E')
bp3 : RMOEN
TM0BC counts up from x'00'. Timer 0 outputs the base cycle pulse set in TM0OC. Then, the 1/3 duty
remote control carrier pulse signal is output. If the RMOEN flag of the RMCTR register is set to "0",
the remote control carrier pulse signal output is stopped.
(6) Set both of the TM0MOD flag and TM0PWM
flag of the TM0MD register to "0" to select
normal timer operation.
(7) Select fosc to clock source by the
TM0CK2-0 flag of the TM0MD register.
(8) Set the base cycle of remote control carrier by
writing x'6C' to the timer 0 compare register
= x'6C' (TM0OC). The set value should be (8 MHz/
73.4 kHz) - 1 = 108(x'6C')
8 MHz is divided to be 73.4 kHz, 2 times
36.7 kHz.
(9) Set the TM0EN flag of the TM0MD register to
"1" to stop the timer 0 counting.
= 1
(10) Set the RMOEN flag of the RMCTR register to
"1" to enable the remote control carrier output.
