20.3.3
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.
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.
