Status register, at address 02h, during the interrupt service routine and then reset the
ALERT mask bit 7 in the Configuration register to logic 0 at the end of the interrupt service
routine (see
In order for the SA56004X to respond to the ARA command, the bit D0 in the ALERT
mode register must be set LOW.
ALERT mask bit 7 and the ALERT mode bit D0 are both LOW for the POR default.
The following events summarize the ALERT output interrupt operation in the SMBus Alert
mode:
Remark: The bit assignment of the returned data from the ARA reading is listed in

Event A: Master senses the ALERT line being LOW.
Event A to B: Master sends a read command using the common 7-bit Alert Response
Address (ARA) of 0001100.
Event A to B: Alerting device(s) return ACK signal and their addresses using the

master can repeat the alert reading process and work up through all the interrupts).
Event B: Upon the successful completion of returning address, the SA56004X resets its
ALERT output (to OFF) and sets the ALERT mask bit 7 in its configuration register.
Event C: Master should read the device status register to identify and correct the
conditions that caused the Alert interruption. The status register is reset.
Event D: Master resets the ALERT mask bit 7 in the configuration register to enable the
device ALERT output interruption.
