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.
