Two types of serial communication interface is incorporated
Asynchronous mode or synchronous mode selectable
Desired bit rate selectable with built-in baud rate generator
Multiprocessor communication function
32-byte data automatically transferrable
Transfer clock selectable among seven types of internal/external clock
Conforms to Phillips I
Single master mode/slave mode
Arbitration lost condition can be identified
Supports two slave addresses
Resolution: 10 bits
Input: 12 channels
High-speed conversion: 13.4 µs minimum conversion time (10 MHz
operation)
Sample-and-hold function
A/D conversion can be activated by software or external trigger
Interrupt occurs when the preset address is found during bus cycle
To-be-trapped addresses can be individually set at three different
locations
60 input/output pins
8 input-only pins
Can be switched for each supporting module
Digital servo circuits on-chip
Input and output circuits
Error detection circuit
