10.5.7 Operation of TMS Measure Input

(1) Outline of TMS measure input

In TMS measure input, the counter starts counting up clock pulses when the timer is actuated by

writing to the enable bit in software. When event input is entered to TMS while the timer is

operating, the counter value is latched into measure registers 0-3. The timer stops at the same

time count is disabled by writing to the enable bit.

A TIN interrupt can be generated by entering a measure signal from an external device. Also,

when the counter overflows, a TMS interrupt can be generated.
