The 16-bit Timer/Counter unit allows accurate program execution timing (event management),
wave generation, and signal timing measurement.
A simplified block diagram of the 16-bit Timer/Counter is shown in
actual placement of I/O pins, refer to
ters, including I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit
locations are listed in section
