Revision A2
Dual-clock slow operation mode: system is operated by the sub-oscillator
(F
OSC
= Fs and Fm is stopped)
Five types of interrupts
Four internal interrupts (Divider0, Divider1, Timer0, Timer1) for W741C260 body;
three internal interrupts (Divider0, Timer0, Timer1) for W741C250 body.
One external interrupt (RC Port) for W741C260 body;
two external interrupts (RC port and
INT
pin) for W741C250 body.
LCD driver output
32 segment x 4 common
Static, 1/2 duty (1/2 bias), 1/3 duty (1/2 or 1/3 bias), 1/4 duty (1/3 bias) driving mode can be
selected
LCD driver output pins can be used as DC output port by code option
Clock source can be main oscillator clock in the single-clock operation mode, or sub-oscillator
clock in the dual-clock operation mode; operation mode is selected by code option
MFP output pin
Output is software selectable as modulating or nonmodulating frequency
Works as frequency output specified by Timer 1
Two built-in 14-bit frequency dividers
Divider0: the clock source is the output of the main oscillator
Divider1: the clock source is the output of the sub-oscillator
Two built-in 8-bit programmable countdown timers
Timer 0: one of two internal clock frequencies (F
OSC
/4 or F
OSC
/1024) can be selected
Timer 1: includes an auto-reload function and one of two internal clock frequencies (F
OSC
or
F
OSC
/64) can be selected, or falling edge of pin RC.0 can be selected (output through MFP pin)
Built-in 18/14-bit watchdog timer selectable for system reset
Enable/Disable the watchdog timer can be controlled by command or by option code;
the control source (command or option code) can be determined by another option code
Powerful instruction set: 118 instructions for W741C260 body
116 instructions for W741C250 body
8-level subroutine (include interrupt) nesting
Up to 1
μ
S instruction cycle (with 4 MHz operating frequency)
Packaged in 80-pin QFP
