Eleven interrupt sources
Four internal interrupts (Divider0, Divider1, Timer 0, Timer 1)
Seven external interrupts (RC.0-3, P1.2(/INT0), Serial Port, P1.3(/INT1))
LCD driver output
40 segments x 16 commons
1/8 or 1/16 duty (selected by code option) 1/5 bias driving mode
Clock source should be the sub-oscillator clock in the dual-clock operation mode
8 level software LCD contrast adjusting
LCD operating voltage source could come from Vdd or Vlcd1-pin input
MFP output pin
Output is software controlled to generate modulating or nonmodulating frequency,
normally as key tone generator
Works as frequency output specified by Timer 1
- Key tone generator
DTMF output pin
Output is one channel Dual Tone Multi-Frequency signal for dialling
8-bit Serial I/O Interface
8-bit transmit/receive mode by internal or external clock source
Two built-in 14-bit frequency dividers
Divider0: the clock source is the main oscillator (Fosc)
Divider1: the clock source is the sub-oscillator (Fs)
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: with auto-reload function and one of two internal clock frequencies (F
OSC
or
F
OSC
/64 or Fs) can be selected (signal output through MFP pin)
Built-in 18/14-bit watchdog timer selectable for system reset determined by code option
Powerful instruction set: 1XX instructions
16-level stack buffer
Package type : 100-pin QFP
