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 of 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 enabled (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.
TIN and TMS interrupt requests can be generated by external measure signal input and counter overflow,
respectively.
