Serial interface

• UART supporting LIN-bus:

1 channel

• 3-wire serial I/O/UARTNote:

1 channel

• 3-wire serial I/O:

1 channel

• 3-wire serial I/O with automatic transmission/reception function: 1 channel

• I2C bus:

1 channel

Multiplier/divider

• 16 bits × 16 bits = 32 bits (multiplication)

• 32 bits ÷ 16 bits = 32 bits remainder of 16 bits (division)

Key interrupt

Key interrupt (INTKR) occurs by detecting falling edge of key input pins (KR0 to KR7).

Reset

• Reset using RESET pin

• Internal reset by watchdog timer

• Internal reset by power-on-clear

• Internal reset by low-voltage detector

On-chip debug function

None
