10. 16-bit Reload Timer
The 16-bit reload timer provides a choice of functions, including internal clock signals that count down in
synchronization with three types of internal clock, as well as an event count mode that counts down at specified
edge detection events in pulse signals input from external pins. This timer defines an underflow as a change in
count value from 0000
H
to FFFF
H
. Thus an underflow will occur when counting from the value “reload register
setting value
+
1”. The choice of counting operations includes reload mode, in which the count setting values is
reloaded and counting continues following an underflow event, and one-shot mode, in which an underflow event
causes counting to stop. An interrupt can be generated at counter underflow, and the timer is DTC compatible.
