9. 8-Bit TimerCounter (TC3, TC4)
9.1 Configuration
TMP86PM29BUG
The TimerCounter 4 is controlled by the TimerCounter 4 control register (TC4CR) and two 8-bit timer registers
(TTREG4 and PWREG4).
Note 1: Do not change the timer register (TTREG4) setting while the timer is running.
Note 2: Do not change the timer register (PWREG4) 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 TC4M, TC4CK and TFF4 settings while the timer is running.
Note 3: To stop the timer operation (TC4S= 1
→
0), do not change the TC4M, TC4CK and TFF4 settings.
To start the timer operation (TC4S= 0
→
1), TC4M, TC4CK and TFF4 can be programmed.
Note 4: When TC4M= 1** (upper byte in the 16-bit mode), the source clock becomes the TC3 overflow signal regardless of the
TC4CK setting.
Note 5: To use the TimerCounter in the 16-bit mode, select the operating mode by programming TC4M, where TC3CR<TC3M>
must be set to 011.
