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 and the diagram in the next page show specifications and a block diagram of TMS, respec-

tively.

× 2

Measure register

16-bit measure register

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.
