Address: 0F039H
Access: R/W
Access size: 8 bits
Initial value: 00H
TM2C is a special function register (SFR) that functions as an 8-bit binary counter.
When write operation to TM2C is performed, TM2C 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 TM2C or high-order TM3C, both the low order and the high order are set to “0000H”.
During timer operation, the contents of TM2C may not be read depending on the conditions of the timer clock and the
system clock.
Table 10-3 shows whether a TM2C read is enabled or disabled during timer operation for each condition of the timer
clock and system clock.
