In event counter mode, the timer counts pulses from an external device or overflows and underflows of
other timers (see Table 12.7). Figure 12.19 shows the TBiMR register in event counter mode.

• External signals input to TBi
• Timer Bj overflow or underflow (j=i-1, except j=2 if i=0)
• Decrement
• When the timer underflows, it reloads the reload register contents and

Set TBiS bit to 0 (stop counting)
Count source input
Count value can be read by reading TBi register
• When not counting and until the 1st count source is input after counting start
• When counting (after 1st count source input)
continues counting

Value written to TBi register is written to both reload register and counter
Value written to TBi register is written to only reload register
(Transferred to counter when reloaded next)
