Interrupt request generation timing When the timer underflows
TBiIN pin function
Read from timer
Write to timer
1. Bits CNT3 to CNT0 in the TCSPR register select no division (n = 0) or divide-by-2n (n = 1 to 15).
2. Wait for one or more count source cycles to write after the count starts.
Contents of the counter
n = contents of the reload
register
TBiS bit in the
TABSR or TBSR
register
IR bit in the TBiIC
register
i = 0 to 5
(Condition) TBiMR register: Bits TMOD1 and TMOD0 are set to 00b (timer mode).
In timer mode, the timer counts an internally generated count source.
Table 15.9 lists specifications of timer mode. Figure 15.27 shows a timer mode operation (Timer B).

The TBiS bit in the TABSR or TBSR register is set to 1 (count starts)
The TBiS bit is set to 0 (count stops)
Programmable I/O port
A read from the TBi register returns a counter value.
• A write to the TBi register while the count is stopped:
• A write to the TBi register while counting:
f1, f8, f2n
The value is written to both the reload register and the counter.
The value is written to the reload register (It is transferred to the counter at the
next reload timing).
fj
When the timer underflows, the contents of the reload register are reloaded
into the counter and the count continues.
