11.3.3 Timer I/O Control Register (TIOR)
The TIOR registers are 8-bit readable/writable registers that control the TGR registers. This
module has a total of eight TIOR registers, two each for channels 0, 3, and 4, one each for
channels 1 and 2.
TIOR should be set while TMDR is set in normal operation, PWM mode, or phase counting mode.
The initial output specified by TIOR is valid when the counter is stopped (the CST bit in TSTR is
cleared to 0). Note also that, in PWM mode 2, the output at the point at which the counter is
cleared to 0 is specified.
When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register
operates as a buffer register.
