Note:
15.3.3
The TIOR registers are 16-bit registers that control the TPU_TO pin. The TPU has four TIOR
registers, one for each channel. The TIOR registers are initialized to H'0000 by a reset, but not
initialized in standby mode, sleep mode, or module standby.
TIOR register settings should be made only when TCNT operation is halted.
Care is required since TIOR is affected by the TMDR setting.
If the counting operation is halted, the initial value set by this register is output from the TPU_TO
pin.

Timer I/O Control Registers (TIOR)
Operation when setting (BFWT, BFB, BFA) = (1, 1, 0) is the same as when setting
(BFWT, BFB, BFA) = (1, 0, 1). However, when the BFB bit is set to 1 (TGRB and TGRD
used together for buffer operation), the setting of (BFWT, BFB, BFA) = (1, 1, 1) should
be made. In this case, the value set in TGRA should also be set in TGRC because
TGRA and TGRC are also used together for buffer operation.
