40-bit Fm+ I
2
C-bus advanced I/O port with RESET, OE and INT
If ALLBNK = 1XX0 1100:
All I/Os configured as outputs in Bank 2 and 3 will be programmed with 1s, overwriting
values programmed in the Output Port registers 2 and 3, while I/Os configured as
outputs in Bank 0, 1, and 4 are programmed with values in Output Port registers 0, 1,
and 4.
7.4.8
MODE - PCA9698 mode selection register
This register allows programming of the PCA9698 modes.
OEPOL bit controls the polarity of OE pin.
–
OEPOL = 0: OE pin is active LOW.
–
OEPOL = 1: OE pin is active HIGH (equivalent to OE pin).
OCH bit selects the I
2
C-bus event where the state of the I/Os configured as outputs
change.
–
OCH = 0: outputs change on STOP command.
–
OCH = 1: outputs change on ACK.
IOAC bit controls the ability of the device to respond to a ‘GPIO All Call’ command
(see
Section 7.6 “GPIO All Call”
for more information), allowing programming of more
than one device at the same time.
–
IOAC = 0: The device cannot respond to a ‘GPIO All Call’ command.
–
IOAC = 1: The device can respond to a ‘GPIO All Call’ command.
Remark:
The ‘GPIO ALL CALL command defined for the PCA9698 is different from
the I
2
C-bus protocol ‘General Call’ command.
SMBA bit controls the capability of the PCA9698 to respond to a SMBAlert command.
–
SMBA = 0: PCA9698 does not respond to an Alert Response Address.
–
SMBA = 1: PCA9698 responds to an Alert Response Address. Bits 5, 6 and 7 are
reserved and must be programmed with 0s.
Unused bits (bits 2, 5, 6 and 7) must be programmed with 0s for proper device
operation.
