10.3 Control
Registers
(1)
TMRn control register 0 (TRnCTL0)
The TRnCTL0 register is an 8-bit register that controls the operation of timer Rn.
This register can be read and written in 8-bit or 1-bit units.
RESET input changes the value of this register to initial setting 00H.
Caution:
When TRnCE = 1, do not rewrite bits other than bit TRnCE of the TRnCTL0 register.

Timer Rn Operation Control
0
Internal operating clock operation disabled (Reset timer Rn asynchronously)
1
Internal operating clock operation enabled
When bit TRnCE is set to “0”, the internal operation clock of timer Rn stops (fixed to low
level), and timer Rn is set asynchronously.
When bit TRnCE is set to “1”, the internal operation of timer Rn is enabled from when bit
TRnCE was set to “1” and count-up is performed. The time until count-up is as listed in
Table 10-2, “TMRn Count Clock and Count Delay,” on page 325.
Remark:
By setting TRnCE = 0 following functions of timer Rn are reset.
•
Internal registers and internal latch circuits other than registers that can be
written to/from the CPU
•
TRnOVF flag and flags in TRnOPT6 register
•
Counter, sub-counter, dead time counter, counter read register, sub-counter
read register
•
TRnCCR0 to TRnCCR5 buffer registers, TRnDTC0 buffer register, and
TRnDTC1 buffer register
•
Timer output (inactive level output)
