In event counter mode, the timer counts how many external signals are applied or how many times
another timer overflows and underflows. (See Table 15.10) Figure 15.21 shows the TBiMR register (i=0
to 5) in event counter mode.

• External signal applied to the TBi
• TBj overflow or underflow signal (j=i-1, except j=2 when i=0, j=5 when i=3)
• The timer decrements a counter value
1/(n+1)
The TBiS bits in the TABSR and TBSR register are set to "1" (starts counting)
The TBiS bit is set to "0" (stops counting)
Programmable I/O port or count source input
The TBi register indicates counter value
• When the timer counter stops, the value written to the TBi register is also written to
• While counting, the value written to the TBi register is written to the reload register
C
When the timer counter underflows, content of the reload register is reloaded into the

(It is transferred to the counter at the next reload timing)
