Timer output mode register m (TOMm)
The TOMm register is used to control the timer output mode of each channel.
When a channel is used for the independent channel operation function, set the corresponding bit of the channel
to be used to 0.
When a channel is used for the simultaneous channel operation function (PWM output), set the corresponding bit
of the master channel to 0 and the corresponding bit of the slave channel to 1.
The setting of each channel n by this register is reflected at the timing when the timer output signal is set or reset
while the timer output is enabled (TOEmn = 1).
The TOMm register can be set by a 16-bit memory manipulation instruction.
The lower 8 bits of the TOMm register can be set with an 8-bit memory manipulation instruction with TOMmL.
Reset signal generation clears this register to 0000H.

Caution
Be sure to clear bits 15 to 4 , 2 to 0 to “0” in TOM0 register. Set to 0000
H
register in TOM1 register.
Remark
m: Unit number (m = 0, 1)
n: Channel number
n = 0 to 3 (n = 0, 2 for master channel)
p: Slave channel number
n = 0, p = 1, 2, 3
n = 2, p = 3
(For details of the relation between the master channel and slave channel, refer to
simultaneous channel operation function
Address: F01BEH, F01BFH (TOM0), F01FEH, F01FFH (TOM1)
After reset: 0000H

Control of timer output mode of channel n

Master channel output mode (to produce toggle output by timer interrupt request signal (INTTMmn))

and reset by the timer interrupt request signal (INTTMmp) of the slave channel)
