Free-run timer
interrupt request
Note: The 16-bit I/O timer contains one 16-bit free-run timer.
The interrupt request number of the 16-bit free-run timer is as follows :
Interrupt request number : 19 (13H)
Prescaler: Takes a fraction of the machine clock, and supplies a count clock to the 16-bit up-counter. One of
four machine clock fractions can be selected by setting the timer counter control status register
(TCCS) .
Timer Counter Register (TCDT) :
This is a 16-bit up-counter. It is possible to read the current counter value of the 16-bit free-run timer
by reading this counter. The counter can be set to an arbitrary value by writing to it while stopped.
Timer Counter Control Status Register (TCCS) :
TCCS selects the divide ratio of a machine clock, executes software clear of counter values. and
enables or disables counter operation. Also TCCS confirms and clears an overflow generation flag,
and enables or disables interruption.
