10. 8-Bit TimerCounter (TC5, TC6)
10.1 Configuration
10.2 TimerCounter Control
The TimerCounter 5 is controlled by the TimerCounter 5 control register (TC5CR) and two 8-bit timer registers
(TTREG5, PWREG5).
TimerCounter 5 Timer Register

PWREG5
(002EH)
R/W
Note 1: Do not change the timer register (TTREG5) setting while the timer is running.
Note 2: Do not change the timer register (PWREG5) setting in the operating mode except the 8-bit and 16-bit PWM modes while
the timer is running.

TC5CK
TC5S
TC5M
Note 1: fc: High-frequency clock [Hz] fs: Low-frequency clock[Hz]
Note 2: Do not change the TC5M, TC5CK and TFF5 settings while the timer is running.
Note 3: To stop the timer operation (TC5S= 1 → 0), do not change the TC5M and TC5CK settings. To start the timer operation
(TC5S= 0 → 1), TC5M and TC5CK can be programmed.
Note 4: To use the TimerCounter in the 16-bit mode, set the operating mode by programming TC6CR<TC6M>, where TC5M must
be fixed to 011.
Note 5: To use the TimerCounter in the 16-bit mode, select the source clock by programming TC5CK. Set the timer start control
and timer F/F control by programming TC6CR<TC6S> and TC6CR<TFF6>, respectively.
Note 6: The operating clock settings are limited depending on the timer operating mode. For the detailed descriptions, see Table
10-1 and Table 10-2.
Note 7: The timer register settings are limited depending on the timer operating mode. For the detailed descriptions, see Table 10-
3.
Note 8: The operating clock fc in the SLOW or SLEEP mode can be used only as the high-frequency warm-up mode.
