MULTIJUNCTION TIMERS
10.6 TML (Input-Related 32-Bit Timer)

10.6.2 Outline of TML Operation
In TML, the timer starts counting upon deassertion of the reset input signal. The counter included in the timer is
a 32-bit up-counter, where when a measure event signal is entered from an external device, the counter value at
that point in time is stored in each 32-bit measure register.
When the reset input signal is deasserted, the counter starts operating with a BCLK/2 clock, and cannot be
stopped once it has started. The counter is idle only when the microcomputer remains reset.
A TIN interrupt request can be generated by external measure signal input. However, no TML counter overflow
interrupts are available.
