Address: 0F035H
Access: R/W
Access size: 8 bits
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 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”.
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 contents of TM1C may not be read depending on the conditions of the timer clock and the
system clock.
Table 10-2 shows whether a TM1C read is enabled or disabled during timer operation for each condition of the timer
clock and system clock.
