10.5 TMS (Input-related 16-bit Timer)
10.5.1 Outline of TMS
TMS (Timer Measure Small) is an input-related 16-bit timer capable of measuring input pulses in
two circuit blocks comprising a total eight channels.
The table below shows specifications of TMS. The diagram in the next page shows a block diagram
of TMS.

10.5.2 Outline of TMS Operation
In TMS, when the timer is started by writing to the enable bit in software, the counter starts
operating. The counter is a 16-bit up-counter, where when a measure signal is entered from an
external device, the counter value is latched into each measure register.
The counter stops counting at the same time count is disabled by writing to the enable bit in
software.
A TIN interrupt can be generated by entering an external measure signal. Also, a TMS interrupt can
be generated by a counter overflow.
