• Manufacturer Part Number: TLE6232
• Description: Smart Six Channel Low-Side Switch
• Manufacturer: INFINEON [Infineon Technologies AG]

- 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.
