Sets the TAU0EN bit of the PER2 register to 1.
Sets the TPS0 register.
Sets the TMRn register (determines operation mode of
channel).
Sets the TISn bit to 1 (f
the count clock (products other than the 78K0R/IB3).
Sets interval (period) value to the TDRn register.
To use the TOn output
(Sets the TOEn bit to 1 only if using TOn output and
Sets the TSn bit to 1.
Set values of TMRn register, TOMn, and TOLn bits
cannot be changed.
Set value of the TDRn register can be changed.
The TCRn register can always be read.
The TSRn register is not used.
Set values of the TO0 and TOE0 registers can be
changed.
The TTn bit is set to 1.
TOEn is cleared to 0 and value is set to TOn bit.
To hold the TOn pin output level
When holding the TOn pin output level is not necessary
The TAU0EN bit of the PER2 register is cleared to 0.
resuming operation.)
Determines the clock frequencies of CK00 and CK01
for channels 0 to 7, and those of CK02 and CK03 for
channels 8 to 11.
Clears the TOMn bit of the TOM0 register to 0 (master
channel output mode).
Clears the TOLn bit to 0.
Sets the TOn bit and determines default level of the
TOn output.
Sets TOEn to 1 and enables operation of TOn.
Clears the port register and port mode register to 0.
The TSn bit automatically returns to 0 because it is a
trigger bit.
The TTn bit automatically returns to 0 because it is a
trigger bit.
Clears TOn bit to 0 after the value to
be held is set to the port register.
Switches the port mode register to input mode.

Power-off status
Power-on status. Each channel stops operating.
Channel stops operating.
(Clock is supplied and some power is consumed.)
The TOn pin goes into Hi-Z output state.
The TOn default setting level is output when the port mode
register is in the output mode and the port register is 0.
TOn does not change because channel stops operating.
The TOn pin outputs the TOn set level.
TEn = 1, and count operation starts.
Counter (TCRn) counts down. When count value reaches
0000H, the value of TDRn is loaded to TCRn again and the
count operation is continued. By detecting TCRn = 0000H,
INTTMn is generated and TOn performs toggle operation.
After that, the above operation is repeated.
TEn = 0, and count operation stops.
The TOn pin outputs the TOn set level.
The TOn pin output level is held by port function.
The TOn pin output level goes into Hi-Z output state.
Power-off status
(Clock supply is stopped and writing to each register is
disabled.)
(Clock supply is started and writing to each register is
enabled.)
Value of TDRn is loaded to TCRn at the count clock input.
INTTMn is generated and TOn performs toggle operation if
the MDn0 bit of the TMRn register is 1.
TCRn holds count value and stops.
The TOn output is not initialized but holds current status.
All circuits are initialized and SFR of each channel is also
initialized.
(The TOn bit is cleared to 0 and the TOn pin is set to port
mode.)
