8-bit Timer
VIII - 8 Control Registers
8.2 Control Registers
Timer 0 to timer 7 and timer 14 to timer 17 consist of the binary counter (TMnBC) and the base register
(TMnBR), and are controlled by the mode register (TMnMD). When the prescaler output is selected as the count
clock source of timer 0 to 7, they should be controlled by the prescaler control register.
8.2.1 Registers
Table: 8.2.1 shows registers that control 8-bit timers.
