RX23W Group 23. Multi-Function Timer Pulse Unit 2 (MTU2a)
23.2.3 Timer I/O Control Register (TIOR)
• MTU0.TIORH, MTU1.TIOR, MTU2.TIOR, MTU3.TIORH, MTU4.TIORH
Note 1. If the IOm[3:0] (m = A, B) bits are changed to an “output prohibited” setting (0000b or 0100b) while output of the low or high level
or toggling of the output in response to compare matches is in progress, the output becomes high-impedance.
• MTU0.TIORL, MTU3.TIORL, MTU4.TIORL
Note 1. If the IOm[3:0] (m = C, D) bits are changed to an “output prohibited” setting (0000b or 0100b) while output of the low or high level
or toggling of the output in response to compare matches is in progress, the output becomes high-impedance.
Note 2. In MTU0, which have no MTIOC0D pin, this bit is reserved. It is read as 0. The write value should be 0.
