TIMERS and TIMER/COUNTERS
OVERVIEW
The KS57C2308/C2316 microcontroller has three timer and timer/counter modules:
— 8-bit basic timer (BT)
— 8-bit timer/counter (TC0)
— Watch timer (WT)
The 8-bit basic timer (BT) is the microcontroller's main interval timer. It generates an interrupt request at a fixed
time interval when the appropriate modification is made to its mode register. The basic timer also functions as
“watchdog” timer and is used to determine clock oscillation stabilization time when stop mode is released by an
interrupt and after a
RESET
.
The 8-bit timer/counter (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, main and subsystem clock
interval timing, buzzer output generation. It also generates a clock signal for the LCD controller.
