3.5.7.1.25 Set General Purpose Output - #SGPO

#SGPO - Set General Purpose Output

SELINT 0 / 1

AT#SGPO[=
[]]

Set command sets the value of the general purpose output pin GPIO2.

Parameter:

0 - output pin cleared to 0 (Low)
1 - output pin set to 1 (High)

Note: the GPIO2 is an OPEN COLLECTOR output, the command sets the
transistor base level, hence the open collector output is negated:
AT#SGPO=0 sets the open collector output High
AT#SGPO=1 sets the open collector output Low
A pull up resistor is required on pin GPIO2.

Note: issuing AT#SGPO is the same as issuing the Read command.

Note: issuing AT#SGPO= is the same as issuing the command
AT#SGPO=0.

AT#SGPO?

Read command reports the #SGPO command setting, hence the opposite
status of the open collector pin in the format:

#SGPO: .

AT#SGPO=?

Test command reports the supported range of values of parameter .

Note

This command is meaningful only for GM862 family

3.5.7.1.26 General Purpose Input - #GGPI

#GGPI - General Purpose Input

SELINT 0 / 1

AT#GGPI[=[

]] Set command sets the general purpose input pin GPIO1.

Parameter:
