Common output:
4 (COM0 to COM3)
Bias terminals for LCD driver:
3 (V1 to V3)
Other functions
Input/output ports:
32 (PAn, PBn, PDn, PEn)
Input ports:
7 (PLn)
• Oscillator pins:
2 (CF1, CF2)

„LCD Controller
• Seven display modes are available (static, 1/2, 1/3, 1/4 duty × 1/2, 1/3 bias)
• Segment output and common output can be switched to general purpose input/output ports.
„Small Signal Detection (MIC signals etc)
• Counts pulses with the level which is greater than a preset value
• 2 bit counter
„Timers
• Timer 0: 16-bit timer / counter with capture register
Mode 0: 2 channel 8-bit timer with programmable 8-bit prescaler and 8-bit capture register
Mode 1: 8-bit timer with 8-bit programmable prescaler and 8-bit capture register
+8-bit counter with 8-bit capture register
Mode 2: 16-bit timer with 8-bit programmable prescaler and 16-bit capture register
Mode 3: 16-bit counter with 16-bit capture register
• Timer 1: PWM / 16-bit timer/counter with toggle output function
Mode 0: 8-bit timer with 8-bit prescaler (and toggle output) +8-bit timer / counter with 8-bit prescaler
(and toggle output)
Mode 1: 2 channel 8-bit PWM with 8-bit prescaler
Mode 2: 16-bit timer/counter with 8-bit prescaler (and toggle output)
(Toggle output also possible using the lower order 8-bits)
Mode 3: 16-bit timer with 8-bit prescaler (and toggle output)
(The lower order 8 bits can be used as PWM output)
