Serial interface
• UART mode supporting LIN-bus:
1 channel
• 3-wire serial I/O mode:
1 channel (none in the
µPD780131, 780132)
• 3-wire serial I/O mode/UART mode
Note: 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 clock monitor
• Internal reset by power-on-clear
• Internal reset by low-voltage detector
ROM correction
