• At reset signal generation
• If TMC0n3 and TMC0n2 are cleared to 00
• If the valid edge of the TI00n pin is input in the mode in which the clear & start occurs when inputting the valid
• If TM0n and CR00n match in the mode in which the clear & start occurs when TM0n and CR00n match
• OSPT0n is set to 1 in one-shot pulse output mode or the valid edge is input to the TI00n pin
The count value of TM0n can be read by reading TM0n when the value of bits 3 and 2 (TMC0n3 and TMC0n2) of
16-bit timer mode control register 0n (TMC0n) is other than 00. The value of TM0n is 0000H if it is read when
TMC0n3 and TMC0n2 = 00.
The count value is reset to 0000H in the following cases.
Caution
CR00n and CR01n are 16-bit registers that are used with a capture function or comparison function selected by
using CRC0n.
Change the value of CR00n while the timer is stopped (TMC0n3 and TMC0n2 = 00).
The value of CR01n can be changed during operation if the value has been set in a specific way. For details, see
7.5.1 Rewriting CR01n during TM0n operation.
These registers can be read or written in 16-bit units.
Reset signal generation clears these registers to 0000H.

TM0n
Even if TM0n is read, the value is not captured by CR01n.
