Section 10 16-Bit Timer Pulse Unit (TPU)
10.3.3
The TIOR registers are 8-bit readable/writable 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.
Care is required as 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.
When TGRC or TGRD is designated for buffer operation, this setting is invalid and the register
operates as a buffer register.
• TIORH_0, TIOR_1, TIOR_2, TIORH_3, TIOR_4, TIOR_5
• TIORL_0, TIORL_3
