10.2.9
The ITU has five 8-bit timer control registers (TCR), one for each channel.
TCR is an 8-bit read/write register that selects the timer counter clock, the edges of the external
clock source, and the counter clear source. TCR is initialized to H'80 or H'00 by a reset and in
standby mode.

Note: * Undefined
Bit 7—Reserved: Bit 7 is read as undefined. The write value should be 0 or 1.

Function
TCR controls the TCNTs. The TCRs have the same functions on all channels.
When channel 2 is set for phase counting mode, setting the CKEG1, CKEG2,
and TPSC2–TPSC0 bits will have no effect.
