CHAPTER 8 16-bit reload timer
■
Operation in Event Count Mode
The operation of the 16-bit reload timer is enabled by setting the timer operation enable bit in the timer
control status register (TMCSR: CNTE) to "1".When the software trigger bit in the timer control status
register (TMCSR: TRG) is set to 1, the 16-bit reload timer is started.When the 16-bit reload timer is started,
the value set in the 16-bit reload register (TMRLR) is reloaded to the 16-bit timer register (TMR), starting
the TMR count operation.After the 16-bit reload timer is started, the edge of the external event clock input
to the TIN pin is detected to perform the TMR count operation.
•
By setting the operation mode select bits in the timer control status register (TMCSR: MOD2 to
MOD0), the detected edge can be selected from the rising edge, falling edge, and both edges.

Note:
The level width of the external event clock signal input to the TIN pin should be at least 4 T
(T: machine cycle).
