SA56004X
Digital temperature sensor with overtemperature alarms
the 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 Figure 6
).
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:
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
I
2
C-bus Arbitration (the device with the lowest address value sends its address first. 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.
Remark: The bit assignment of the returned data from the ARA reading is listed in
Table 17
. If none of the devices on the bus is alerted, then the returned data from ARA
reading is FFh (1111 1111).
