9. 8-Bit TimerCounter (TC3, TC4)
9.1 Configuration
TMP86CH47SUG
9.2
TimerCounter Control
The TimerCounter 3 is controlled by the TimerCounter 3 control register (TC3CR) and two 8-bit timer registers
(TTREG3, PWREG3).
Note 1: Do not change the timer register (TTREG3) setting while the timer is running.
Note 2: Do not change the timer register (PWREG3) setting in the operating mode except the 8-bit and 16-bit PWM modes while
the timer is running.
Note 1: fc: High-frequency clock [Hz] fs: Low-frequency clock[Hz]
Note 2: Do not change the TC3M, TC3CK and TFF3 settings while the timer is running.
Note 3: To stop the timer operation (TC3S= 1
→
0), do not change the TC3M, TC3CK and TFF3 settings. To start the timer oper-
ation (TC3S= 0
→
1), TC3M, TC3CK and TFF3 can be programmed.
Note 4: To use the TimerCounter in the 16-bit mode, set the operating mode by programming TC4CR<TC4M>, where TC3M must
be fixed to 011.
Note 5: To use the TimerCounter in the 16-bit mode, select the source clock by programming TC3CK. Set the timer start control
and timer F/F control by programming TC4CR<TC4S> and TC4CR<TFF4>, respectively.
Note 6: The operating clock settings are limited depending on the timer operating mode. For the detailed descriptions, see Table
9-1 and Table 9-2.
