F75363
6.4.3 Alert Response Address mode
If ALERT# is connected to one or more ALERT# outputs of SMBus compatible devices, the master may send an ARA
command to ask that which device is pulling ALERT# to low. When the ALERT# is pulled to low by F75363 and F75363
receives the ARA command sent by the master, F75363 will send its address to the master. The F75363 will reset its
ALERT# output and set the ALERT Mask bit once the master acknowledges its response of device address. The master
may read F75363’s status registers to check what the triggering conditions occur. At the end of interrupt service routine, the
master has to reset ALERT Mask bit in configuration register. Note that the triggering conditions do not include BUSY and
OPEN status in Configuration Register (index 02h). The ARA, 000 1100, is a general call address and is defined in SMBus
specifications. No devices should be assigned to this address.
