Serial interface
SIO0 : 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 to 256-bits)
SIO1 : 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)
■
AD converter
8-bits × 15-channels
■
Remote control receiver circuit (connected to P73/INT3/T0IN terminal)
Noise rejection function (noise rejection filter’s time constant can be selected from 1/32/128 tCYC)
■
Watchdog timer
The watching time period is determined by an external RC.
Watchdog timer can produce interrupt or system reset
■
Interrupts : 18 sources, 10 vectors
1. Three priority (low, high and highest) multiple interrupts are supported.
During interrupt handling, an equal or lower priority interrupt request is postponed.
2. If interrupt requests to two or more vector addresses occur at once, the higher priority interrupt takes
precedence. In the case of equal priority levels, the vector with the lowest address takes precedence.
No.
