11. 16-bit Timer/Event Counters (TMRBs)
Each of the thirty-six channels (TMRB00 through TMRB23) has a multi-functional 16-bit timer/event
counter. TMRBs operate in the following four operation modes:
•
•
•
•
Each channel consists of a 16-bit up-counter, two 16-bit timer registers (one of which is
double-buffered), two 16-bit capture registers, two comparators, a capture input control, a timer
flip-flop and its associated control circuit.
controlled by a register.
Each channel (TMRB00∼TMRB23) functions independently and the channels operate in the same
way, except for the differences in their specifications as shown in Table 11.1 and the two-phase pulse
count function. Therefore, the operational descriptions here are only for TMRB14 and for the
two-phase pulse count function (TMRB0C, TMRB12).
The use of the capture function allows TMRBs to operate in three other modes:
16-bit interval timer mode
16-bit event counter mode
16-bit programmable square-wave output (PPG) mode
Two-phase pulse input counter mode (quad/normal-speed, TMRB0C and TMRB12 only).
