<Registers of each channel> n: Channel number (n = 0 to 7)
(12) Timer data register 0n (TDR0n)
(13) Timer counter register 0n (TCR0n)
(14) Timer mode register 0n (TMR0n)
(15) Timer status register 0n (TSR0n)
(16) Input switch control register (ISC) (channel 7 only)
This is the data register of channel n. In the interval timer mode, it functions as a compare register (that sets
an interval period). In the capture mode, it functions as a capture register (that stores a captured value).
This is the counter register of channel n. It counts down in the interval timer mode and counts up in the
capture mode.
This register sets an operation mode of channel n. It is used to select an operating clock (MCK), a count clock,
whether the timer operates as the master or a slave, a start trigger and a capture trigger, the valid edge of the
timer input, and an operation mode (interval, capture, event counter, one-count, or capture & one-count).
This register indicates the overflow status of the timer/counter of channel n.
This register is used to change the timer input signal of channel 7 to a signal input from the serial input pin
(RxD3) of UART3. It is used to realize LIN-bus communication in combination with the serial array unit (SAU).
