Address: 0F031H
Access: R/W
Access size: 8 bits
Initial value: 00H
TM0C is a special function register (SFR) that functions as an 8-bit binary counter.
When write operation to TM0C is performed, TM0C is set to “00H”. The data that is written is meaningless.
In 16-bit timer mode and 16-bit timer frequency measurement mode, if write operation is performed to either the
low-order TM0C or high-order TM1C, both the low-order and the high-order are set to “0000H”.
During timer operation, the contents of TM0C may not be read depending on the conditions of the timer clock and the
system clock.
Table 10-1 shows whether a TM0C read is enabled or disabled during timer operation for each condition of the timer
clock and system clock.

Read enabled. However, to prevent the reading of undefined data
during incremental counting, read TM0C twice and check that the
results match.
