10.6.7 Operation of TML Measure Input

(1) Outline of TML measure input

In TML measure input, when the reset input signal is deasserted, the counter starts counting up synchro-

nously with the count clock. Upon event input to measure registers 0–3, the counter value is latched into

each measure register.

A TIN interrupt request can be generated by measure signal input from an external device. However, no

TML counter overflow interrupts are available.
