The TMU has the following registers. Refer the section 23, List of Registers, for the addresses and
access size for these registers.
• Timer start register (TSTR)
• Timer constant register 0 (TCOR0)
• Timer counter 0 (TCNT0)
• Timer control register 0 (TCR0)
• Timer constant register 1 (TCOR1)
• Timer counter 1 (TCNT1)

14.2.1
The timer start register (TSTR) selects whether to run or halt the timer counters (TCNT) for
channels 0 to 2.
TSTR is an 8-bit readable/writable register. It is initialized to H'00 by a power-on reset or manual
reset. It is initialized in standby mode when the multiplication ratio of PLL circuit 1 (PLL1) is
changed or when the MSTP2 bit in STBCR is set to 1.

Counter Start 2
Selects whether to run or halt TCNT2.
0: TCNT2 count halted
1: TCNT2 counts
Counter Start 1
Selects whether to run or halt TCNT1.
0: TCNT1 count halted
1: TCNT1 counts
