• UART mode supporting LIN-bus:
• 3-wire serial I/O mode:

(None in the PD780143, 780144)
• 3-wire serial I/O mode with automatic transmit/receive function: 1 channel
• 3-wire serial I/O mode/UART mode
• 16 bits × 16 bits = 32 bits (multiplication)
• 32 bits ÷ 16 bits = 32 bits remainder of 16 bits (division)

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