Address: 0F03DH
Access: R/W
Access size: 8 bits
Initial value: 00H
TM3C is a special function register (SFR) that functions as an 8-bit binary counter.
When write operation to TM3C is performed, TM3C 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 (TM2C) or high-order (TM3C), both the
low order and the high order are set to “0000H”.
When reading TM3C in 16-bit timer mode, be sure to read TM2C first since the count value of TM3C is stored in the
TM3C latch when TM2C is read.
During timer operation, the contents of TM3C may not be read depending on the conditions of the timer clock and the
system clock.
Table 11-4 shows whether a TM3C 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 consecutively TM3C twice
until the last data coincides the previous data.
