Note: When TGRC or TGRD is designated for buffer operation, this setting is invalid and the
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.
