As a register, interrupt detected state is “1” and cleared state is “0”. When multiple interrupt sources are
activated, the OR operated result is indicated as IC external INT1/0 pin output.
As an external INT1/0 pin output, open drain output interrupt detected state is “Low” and cleared state is “Hi-
Z”, while INT1/0 pin CMOS push-pull output interrupt detected state is “Low” and cleared state is “High”.
Table 32.
INT1/0 pin output control
INT1/0 interrupt function is supposed to be cleared before start monitoring any desired status because INT1/0
status may have been changed before monitoring activation.
Register Auto Checksum diagnosis
Register values checksum is continuously calculated as R_CKSUM_RVAL.
