Starting timer 1 counting with timer 0 match output
Set the 8-bit timer mode and set the timer 0 comparator
output as the timer 1 input clock.
Figure 3.8 (10)
Output inversion with software
The timer flipflop value can be inverted regardless of
timer operation.
Writing 00 to FF1C (bit 3 and 2 of TFFCR at memory
address FFC6) inverts the TFF1 value. Writing 00 to
FF3C (bits 7 and 6 of TFFCR at memory address
FF3C) inverts the TFF3 value.
Timer Flipflop initial setting
The timer flipflop initial value can be set to either “0” or
“1” regardless of timer operation.
For example, write 10 to FF1C (bits 3 and 2 of TFFCR)
at memory address FF1C to set TFF1 to “0” and write
01 to memory address FF1C to set TFF1 to “1”.
Note:
Timer Flipflop and timer register values cannot
be read.

16-Bit Timer Mode
16-bit interval timers can be created by using timers 0
and 1 as a pair and timers 2 and 3 as a pair.
Timers 0 and 1, and timers 2 and 3 have the same
operation, so timers 0 and 1 are used here for explanatory
purposes.
Cascade connect timers 0 and 1 and set bits 7 and 6
of the timer 0 and 1 mode register T01MOD to “00” to
enable use as a 16-bit interval timer.
When the 16-bit timer mode is set, the timer 0 over-
flow is used as the timer 1 input clock regardless of the
T1CLK (bits 3 and 2 of T01MOD) setting value. Table
3.8 (2) shows the relationship between timer (interrupt)
cycles and input clock selection.
