PCA9698
40-bit Fm+ I2C-bus advanced I/O port with RESET, OE and INT
7.2 Alert response, GPIO All Call and Device ID addresses
Three other different addresses can be sent to the PCA9698.
Alert Response address: allows to perform an ‘SMBus Alert’ operation as defined in
the SMBus specification. This address is always used to perform a Read operation.
See Section 7.11 “SMBus Alert output (SMBALERT)” for more information.
GPIO All Call address: allows to program several Advanced GPIO devices at the
same time. This address is always used to perform a Write operation. See Section 7.6
“GPIO All Call” for more information.
Device ID address: allows to read ID information from the device (manufacturer, part
identification, revision). See Section 7.5 “Device ID - PCA9698 ID field” for more
information.
7.3 Command register
Following the successful acknowledgement of the slave address + R/W bit, the bus
master will send a byte to the PCA9698, which will be stored in the Command register.
The lowest 6 bits are used as a pointer to determine which register will be accessed.
Registers are divided into 2 categories: 5-bank register category, and 1-bank register
category.
Only a command register code with the 7 least significant bits equal to the 28 allowable
values as defined in Table 3 “Register summary” will be acknowledged. Reserved or
undefined command codes will not be acknowledged. At power-up, this register defaults
to 80h, with the AI bit set to ‘1’, and the lowest 7 bits set to ‘0'.
During a write operation, the PCA9698 will acknowledge a byte sent to the OP, PI, IOC,
MSK, OUTCONF, ALLBNK, and MODE registers, but will not acknowledge a byte sent to
the IPx registers since these are read-only registers.
