Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) and Multi-Function Timer Pulse Unit 2S (MTU2S)
10.3.3 Timer I/O Control Register (TIOR)
The TIOR registers are 8-bit readable/writable registers that control the TGR registers. The MTU2
has a total of eleven TIOR registers, two each for channels 0, 3, and 4, one each for channels 1 and
2, and three (TIORU_5, TIORV_5, and TIORW_5) for channel 5.
TIOR should be set when TMDR is set to select 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.
