Section 11 8-Bit Timers
TLR_4 and TLR_5, or TLR_6 and TLR_7 comprise a single 16-bit register, and can be accessed
simultaneously by word access.
TLR is initialized to H'00 by a reset or in hardware standby mode.

11.11.1 Interval Timer Operation
When the ARSL bit in TCR is set to 0, the timer operates as an interval timer.
After a module stop mode is canceled, the timer continues incrementation as an interval timer
without stopping because TCNT is initialized to H'00 and TLR is cleared to 0 by a reset. The input
clock source can be selected from 14 internal clocks output from the prescaler unit and an external
clock from the TMCI4 input pin, using the CKS2 to CKS0 bits in TCR.
When a clock is input after the TCNT value has been H'FF, the timer overflows and OVF in TCR
is set to 1. At this time, if OVIE in TCR is 1, an interrupt is generated.
When an overflow occurs, the TCNT count value is cleared to H'00 and TCNT restarts
incrementation. If a value is set to TLR during interval timer operation, the value is also written to
TCNT.
This operation timing is shown in figure 11.14.
