16-bit Timer/Event Counters (TMRBs)
Each of the eighteen channels (TMRB0 through TMR11) has a multi-functional, 16-bit timer/event counter.
TMRBs operate in the following four operation modes:
•
•
•
•
The use of the capture function allows TMRBs to operate in three other modes:
Each channel consists of a 16-bit up-counter, two 16-bit timer registers (double-buffered), two 16-bit capture
registers, two comparators, a capture input control, a timer flip-flop and its associated control circuit. Timer
operation modes and the timer flip-flop are controlled by a 13-byte register.
Each channel (TMRB0 through TMRB11) functions independently and while the channels operate in the same
way, there are differences in their specifications as shown in Table 11.1. Therefore, the operational descriptions
here are for TMRB0 only.
(1) The flip-flop output of TMRB 0, TMRB 8 and TMRB 10 can be used as the capture trigger of other
(2) The start trigger of the timer synchronous mode (with TBxRUN)
16-bit interval timer mode
16-bit event counter mode
16-bit programmable square-wave output (PPG) mode (simultaneous output in units of four channels can
be programmed)
Timer synchronous mode
The channels shown below are used as the capture or start trigger.
• Frequency measurement mode
• Pulse width measurement mode
• Time difference measurement mode
