Reset of the Diagnostic Register DIA_REG
On the following conditions DIA_REG is reset:
- DI high
- EN low
- With the rising edge of the SS-signal after the SPI-Instruction RD_DIA.
- When the voltage on DMS exceeds the threshold for detecting SPI-Mode.
(after undervoltage condition)
- Undervoltage on VS (< 5,0V) sets Bit 0 .... Bit 3 of DIA_REG to 0000.
- If UB rises over about the undervoltage level, the Bits of DIA_REG are restored
(when VS internal or DMS > 3,5V)
