Parameter Description
Parameter returned by the AT^SSPI? read command.
Indicates whether or not the I²C or SPI 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.
[0] Not connected (channel closed). All following parameters are the factory set-
tings ^SSPI: 0,0010,0000,0000.
1 Connected (channel open, ME in data mode). All following parameters are the
values currently used, for example ^SSPI: 1,0010,0000,0000.
Parameter <basicConfiguration> is a 16 bit word which contains four subparameters to control the follow-
ing functions:
For SPI only:
0000 Length of SPI word = 8 bits
For SPI only: Parameter <extendedSpiConfiguration> is a 16 bit word which contains four subparameters
to control the following functions:
<connectionState>
