Note: When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register operates as a buffer
register.
The TIOR registers are 8-bit registers that control the TGR registers. The TPU has eight TIOR registers, two each for
channels 0 and 3, and one each for channels 1, 2, 4, and 5. The TIOR registers are initialized to H'00 by a reset, and in
hardware standby mode.
Care is required since TIOR is affected by the TMDR setting. 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.
