TIMERS and TIMER/COUNTERS
OVERVIEW
There are three timer and timer/counter function modules:
— 8-bit basic timer (BT)
— 8-bit timer/counter 0 (TC0)
— Watch timer (WT)
The 8-bit basic timer (BT) is the microcontroller's main interval timer. It generates a interrupt request at a fixed
time interval by making the appropriate modification to the mode register.
The basic timer also functions as a 'watchdog' timer and is used to determine clock oscillation stabilization time
when stop mode is released by an interrupt or a
RESET.
The 8-bit timer/counter 0 (TC0) is programmable timer/counter that is used primarily for event counting and for
clock frequency modification and output. In addition, TC0 generates a clock signal that can be used by the serial
I/O interface.
The watch timer (WT) module consists of an 8-bit watch timer mode register, a clock selector, and a frequency
divider circuit. Watch timer functions include real-time and watch-time measurement, system clock interval
timing, and generation of buzzer output.
