SO:
SO:
SI - Serial Input. Serial data bits are shifted in at this pin, the most significant bit (MSB) first. SI infor-
mation is read in on the falling edge. Input data is latched in the SPI shift register and then transferred
to the internal registers of the logic.
The input data consist of 16 bit, made up of x control bits and y data bits. The control bits are used
address the desired SPI register and the data bits are used to program in user-specified settings.
SO - Serial Output. Diagnostic data bits are shifted out serially at this pin, the most significant bit
(MSB) first. SO is in a high impedance state until the CS pin goes to a logic low state. New diagnostic
data will appear at the SO pin following the rising edge.

Reads out the diagnosis register. This command has no other influence on the device.
With the next SO data frame the content of the addressed register will be sent.
Resets back all internal registers. Logic registers to default and Fault registers to no
error.
The data of the SI word will be written to the addressed register.
If the first 8 bit of the SI word contains an invalid command, it will not result in any re-
action by the TLE 7230 R (register value change, switching channels, ...). Additionally
an LàH of Chip Select (CS) will not reset the diagnosis register.
