„VFD Automatic Display Controller
• Programmable segment/digit output pattern
Output can be switched between digit/segment waveform output
(pins 9 to 23 can be used for output of digit waveforms).
parallel-drive available for large current VFD.
• 16-step dimmer function available
„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 4: 8-bit timer with 6-bit prescaler
• Timer 5: 8-bit timer with 6-bit prescaler
• 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 can be selected to occur at one of five different times.
• Day and time counter
1) Using with a base timer, it can be used as 65000 day + minute + second counter.
„SIO
• SIO 0: 8-bit synchronous serial interface
1) LSB first /MSB first function available
2) Internal 8-bit baud-rate generator (maximum transmit clock period 4/3 tCYC)
3) Consecutive automatic data communication
(1 to 256 bits (communication available for each bit) (stop and reopening available for each byte))
• SIO 1: 8-bit asynchronous/synchronous serial interface
Mode 0: Synchronous 8-bit serial IO (2-wire or 3-wire, transmit clock 2 to 512 tCYC)
Mode 1: Asynchronous serial IO (half duplex, 8 data bits, 1 stop bit, baud rate 8 to 2048 tCYC)
Mode 2: Bus mode 1 (start bit, 8 data bits, transmit clock 2 to 512 tCYC)
Mode 3: Bus mode 2 (start detection, 8 data bits, stop detection)
