11.11.2 Automatic Reload Timer Operation
When the ARSL bit in TCR is set to 1, the timer operates as an automatic reload timer.
When a reload value is set to TLR, the value is also loaded to TCNT simultaneously, and TCNT
starts incrementation from the value.
If a clock is input after the TCNT count value reaches H'FF, the timer overflows, the TLR value is
written to TCNT, and incrementation is continued from the value. Therefore, the overflow cycle
can be set within the range from 1 to 256, using a TLR value.
Clock sources and interrupts in automatic reload operation are the same as those in interval
operation. If TLR is re-set during automatic reload operation, the value is also set to TCNT.
This operation timing is shown in figure 11.15.

TCNT value
The channel relationship for cascaded connection is shown in figure 11.16.
When accessing beyond the word area, for example, when a cascaded connection including
channels 5 and 6 is created as shown in (3), and (6) to (8) in the figure, the counter value of the
lower channel is read when TCNT5 is read, and the data is stored in the TCNT register.
For case (7) where channels 5 to 7 are cascaded, the counter values of channels 6 and 7 are
read when TCNT5 is read, and the data is stored in TCNT6/7 registers. Accordingly, when
reading cascaded TCNT, read from the upper channel.
