Pins
This section describes the pins of the 16-bit reload timer and shows the block
diagram of these pins.
■ Pins of 16-bit Reload Timer
The pins of the 16-bit reload timer are namely the TIn and TOn pins.
● TIn pin
This pin is used both as a general-purpose I/O port and as the external pulse input pin for the
counter (TIn).
TIn:
● TOn pin
This pin is used both as a general-purpose I/O port and as the output pin of the 16-bit reload
timer (TOn).
TOn: This pin outputs waveforms of the 16-bit reload timer.
MN702-00009-1v0-E
Any pulse edge input to this pin is counted during counter operation. To use it as the
external pulse input pin in counter operation, set the corresponding bit in the port
direction register (DDR) to "0".
When this pin is used as the 16-bit reload timer output pin, regardless of the setting of
the
port
direction
register
(TMCSRLn:OUTE = 1) automatically makes this pin function as the 16-bit reload timer
output pin to output the waveforms.
