(5) Ports
- Input/output ports
Data direction programmable for each bit individually :
Data direction programmable in nibble units :
(When N-channel open drain output is selected, data can be input in bit units.)
- Input ports :
- LCD ports
Segment output :
Common output :
Bias terminals for LCD driver
Other functions
Input/output ports :
Input ports :
- Oscillator pins :
- Reset pin :
- Power supply :
(6) 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.
(7) Small signal detection (MIC signals etc)
- Counts pulses with the level which is greater than a preset value
- 2 bit counter
(8) 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 with toggle output function
Mode 0: 2 channel 8 bit timer (with toggle output)
Mode 1: 2 channel 8 bit PWM
Mode 2: 16 bit timer (with toggle output) Toggle output from lower 8 bits is also possible.
Mode 3: 16 bit timer (with toggle output) Lower order 8 bits can be used as PWM.
- Base Timer
1) The clock signal can be selected from any of the following :
Sub-clock (32.768kHz crystal oscillator), system clock, and prescaler output from timer 0
2) Interrupts of five different time intervals are possible.
(9) Serial-interface
- SIO 0: 8 bit synchronous serial interface
1) LSB first / MSB first is selectable
2) Internal 8 bit baud-rate generator (fastest clock period 4 / 3 Tcyc)
3) Consecutive automatic data communication (1-256 bits)
- SIO 1: 8 bit asynchronous / synchronous serial interface
Mode 0: Synchronous 8 bit serial IO (2-wire or 3-wire, transmit clock 2–512 Tcyc)
Mode 1: Asynchronous serial IO (half duplex, 8 data bits, 1 stop bit, baud rate 8–2048Tcyc)
Mode 2: Bus mode 1 (start bit, 8 data bits, transmit clock 2–512 Tcyc)
Mode 3: Bus mode 2 (start detection, 8 data bits, stop detection)
