19.7AT^SSPI Serial Protocol Interface

The AT^SSPI command enables the module to be connected to external I²C devices. The I²C datastream is mapped through an internal I²C driver to and from an ASCII hex protocol which can be exchanged with an exter- nal application via V24.

The AT^SSPI write command configures and activates the I²C interface and changes from command mode into data mode. All values must be given in hexadecimal format (0 - 9, A - F) without "0x". For details on data mode please refer to Section 19.7.2, Transmitting Data over AT Interface.

Parameter Description

<connectionState>(num)

Parameter returned by the AT^SSPI? read command.

Indicates whether or not the I²C channel is used. When the channel is open and the ME is in data mode, the read command can only be used if one of the remaining interfaces is available. For example, when the channel was opened on ASC0, you can use ASC1, MUX channels or USB to check the status.

[0](&F)	Not connected (channel closed). All following parameters are the factory set-
	tings AT^SSPI=0,0010,0000,0000.
1	Connected (channel open, ME in data mode). All following parameters are the
	values currently used, for example AT^SSPI=1,0010,FFFF,FFFF.

<basicConfiguration>(num)

Parameter <basicConfiguration> is a 16 bit word which contains four subparameters to control the follow- ing functions:
