Remark
Sets TOEmp (slave) to 1 (only when operation is
resumed).
The TSmn (master) and TSmp (slave) bits of the TSm
register are set to 1 at the same time.
Set values of the TMRmn and TMRmp registers,
TOMmn, TOMmp, TOLmn, and TOLmp bits cannot be
changed.
Set values of the TDRmn and TDRmp registers can be
changed after INTTMmn of the master channel is
generated.
The TCRmn and TCRmp registers can always be read.
The TSRmn and TSRmp registers are not used.
Set values of the TOm and TOEm registers can be
changed.
The TTmn (master) and TTmp (slave) bits are set to 1 at
the same time.
TOEmp of slave channel is cleared to 0 and value is set
to the TOmp bit.
To hold the TOmp pin output levels
When holding the TOmp pin output levels is not
necessary
The TAU0EN bit, TAU1ENbit of the PER0 register is
cleared to 0.
Switches the port mode register to input mode.
When m = 0: n = 0, 2, 4, 6
When m = 1: n = 0, 2
m: Unit number, n: Channel number, p: Slave channel number (p = n+1)
The TSmn and TSmp bits automatically return to 0
because they are trigger bits.
The TTmn and TTmp bits automatically return to 0
because they are trigger bits.
Clears TOmp bit to 0 after the value to
be held is set to the port register.

Software Operation
CHAPTER 7 TIMER ARRAY UNIT
User’s Manual U18432EJ5V0UD
TEmn = 1, TEmp = 1
The counter of the master channel loads the TDRmn
value to TCRmn, and counts down. When the count
value reaches TCRmn = 0000H, INTTMmn output is
generated. At the same time, the value of the TDRmn
register is loaded to TCRmn, and the counter starts
counting down again.
At the slave channel, the value of TDRmp is loaded to
TCRmp, triggered by INTTMmn of the master channel,
and the counter starts counting down. The output level of
TOmp becomes active one count clock after generation of
the INTTMmn output from the master channel. It
becomes inactive when TCRmp = 0000H, and the
counting operation is stopped.
After that, the above operation is repeated.
TEmn, TEmp = 0, and count operation stops.
The TOmp pin outputs the TOmn set level.
The TOmp pin output levels is held by port function.
The TOmp pin output levels go are into Hi-Z output state.
Power-off status
When the master channel starts counting, INTTMmn is
generated. Triggered by this interrupt, the slave
channel also starts counting.
TCRmn and TCRmp hold count value and stops.
The TOmp output is not initialized but holds current
status.
All circuits are initialized and SFR of each channel is
also initialized.
(The TOmp bit is cleared to 0 and the TOmp pin is set
to port mode.)
