SCI3: 8-bit synchronous/asynchronous serial interface
Incorporates multiprocessor communication function
Can be used as a 10-bit D/A converter by connecting to an external low-
pass filter.
8-channel analog input pins
Conversion time: 31/φ or 62/φ per channel
Choice of four duty cycles (static, 1/2, 1/3, or 1/4)
Segment pins can be switched to general-purpose port function in 4-bit units
An internal reset signal can be issued at power-on by connecting an
external capacitor.
Monitors the power supply voltage and issues an internal reset signal or
interrupt if the voltage goes below or above a specified range.
