AIPC_CFG0_W
WO
0xXX
-
Will write
input data to the configuration
register 6 of PCA9555. The register configures
the direction of the I/O pins where a bit value
of 1 defines a pin as an input. The API default
value is 0xFF. (All pins are defined as input)
AIPC_CFG1_W
WO
0xXX
-
Will write
input data to the
configuration
register 7 of PCA9555. The register configures
the direction of the I/O pins where a bit value
of 1 defines a pin as an input. The API default
value is 0x8F. (Pin 4-6 defined as output).
AIPC_R

_GPI
RO
-
1 byte
Will read r
egister 0 of
PCA9555
.
Bit 7 - If high, secondary power is present.
Bit 6 – If high, primary power is present.
Bit 5 – Digital Input (DI2)
Bit 4 – Digital Input (DI1)
Bit 3-0 – Reserved.
AIPC_K2_EN
WO
-
-
Will activate K2
relay
,
thus connecting pin
“COM” to “NO” on “X1-DIG-OUT” port (5 pins
connector).
AIPC_K2_DIS
WO
-
-
Will deactivate K2
relay, th
u
s connecting pin
“COM” to “NC” on “X1-DIG-OUT” port. (5 pins
connector).
AIPC_HS1_EN
WO
-
-
Will activate HS1
switch, thus connecting
“Out+” to “OUT-“ on “X1-DIG-OUT”. Note that
HS_EN must also be active to achieve this.
AIPC_HS1_DIS
WO
-
-
Will deactivate HS1
switch, thus disconnecting
“Out+” from “OUT-“ on “X1-DIG-OUT”. Note
that HS_DIS will also deactivate HS1 switch.
AIPC_HS2_EN
WO
-
-
Will activate HS2
switch, thus connecting
“COM” to “NC“ on “X1-DIG-OUT” (4 pins
connector).
AIPC_HS2_DIS
WO
-
-
Will deactivate HS2
switch, thus disconnecting
“COM” from “NC“ on “X1-DIG-OUT” (4 pins
connector).
