- Read back of SCON_REG (SCON bits 6 to 1 and two high bits)

- Read back of MUX_REG (MUX information for channel 6 to 1 and two high bits)

- Diagnostic information of channel 4 to 1 (2 bits per channel)

On a writing access always the full diagnostic information of the 6 channels (2 bit per channel)

and the over-temperature and common fault bit is performed.

Invalid instruction/access:

An instruction is invalid, if the following condition is fulfilled:

- an unused instruction code is detected (see tables with SPI instructions).

If an invalid instruction is detected, a writing access on a register of TLE6232 GP is not allow-

wed. In addition an access is invalid if the number of SPI clock pulses counted during active

CS differs from exactly 16 clock pulses (falling edges are counted).

- On a writing access the received data is only taken over into the internal registers and

- the fault register is only cleared by the RD_DIAG command,

if exactly 16 SPI clock pulses were counted while CS active.
