In timer mode, the timer counts an internally generated count source (see Table 14.9). Figure 14.20
shows the TBiMR register (i=0 to 5) in timer mode.

• The timer decrements a counter value
1/(n+1)
The TBiS bits in the TABSR and TBSR registers are set to "1" (starts counting)
The TBiS bit is set to "0" (stops counting)
Programmable I/O port
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
1
When the timer counter underflows, content of the reload register is reloaded into the
both reload register and counter
(It is transferred to the counter at the next reload timing)
