GPIO direction control
Integer
This is an integer representing a bit mask indicating which GPIO bits are configured for outputs. Only
bits for which the GPIO bit mask is 1 are valid. A 1 indicates the GPIO bit is an output, a 0 indicates
an input.
GPIO data
Integer
This is an integer representing a bit mask indicating the GPIO bits status. On a read, the current
value of the input pins is returned. Output bits return the last value set. On a write, bits configured as
outputs are set to the value given by the corresponding mask bit. For input bits, a write has no effect.
GPIO trigger mask
Integer
This value is an integer representing a 32 bit mask expressed in hex digits. The mask is encoded as
follows:

TRIG9
GPIO1

N/A
TRIG1
GPIO1
1
A value of 1 indicates the corresponding GPIO trigger condition is enabled. A value of 0 indicates the
correspon ding GPIO trigger condition is disabled. For example a hex value of 4 represents GPIO3 0
to 1 transition (TRIG3) is enabled as a trigger.
GPIO transmit string table index
Integer
This value is the index into the GPIO message table for trigger number n. For the SX-550, this
always returns n as its value.
