TAU
default
setting
Sets the TAUmEN bit of peripheral enable registers 0
(PER0) to 1.
Sets timer clock select register m (TPSm).
Determines clock frequencies of CKm0 and CKm1.
Channel Sets the corresponding bit of the noise filter enable
default register 1 (NFEN1) to 1.
setting
Sets timer mode register mn, mp (TMRmn, TMRmp) of
two channels to be used (determines operation mode of
channels).
An output delay is set to timer data register mn (TDRmn)
of the master channel, and a pulse width is set to the
TDRmp register of the slave channel.
Sets slave channel.
The TOMmp bit of timer output mode register m
(TOMm) is set to 1 (slave channel output mode).
Sets the TOLmp bit.
Sets the TOmp bit and determines default level of the
TOmp output.
Sets the TOEmp bit to 1 and enables operation of TOmp.
Clears the port register and port mode register to 0.

Software Operation
CHAPTER 6 TIMER ARRAY UNIT
Hardware Status
Input clock supply for timer array unit 0 is stopped.
(Clock supply is stopped and writing to each register is
disabled.)
Input clock supply for timer array unit 0 is supplied. Each
channel stops operating.
(Clock supply is started and writing to each register is
enabled.)
Channel stops operating.
(Clock is supplied and some power is consumed.)
The TOmp pin goes into Hi-Z output state.
The TOmp default setting level is output when the port
mode register is in output mode and the port register is 0.
TOmp does not change because channel stops operating.
The TOmp pin outputs the TOmp set level.
