Address: 0F035H
Access: R/W
Access size: 8-bit
Initial value: 00H
TM1C is a special function register (SFR) that functions as an 8-bit binary counter.
When write operation to TM1C is performed, TM1C is set to “00H”. The data that is written is meaningless.
In 16-bit timer 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”.
When reading TM1C in 16-bit timer mode, be sure to read TM0C first since the count value of TM1C is stored in the
TM1C latch when TM0C is read.
During timer operation, the TM1C content may not be read depending on the conditions of the timer clock and the
system clock.
Table 9-2 shows whether a TM1C read is enabled or disabled during timer operation for each condition of the timer
clock and system clock.
