Device mode
Note:
To leave FAIL SAVE the LHOMEN-bit in ControlRegister (Addr.: hex00, Bit 0) has to be set
to ‘1’. FAIL SAVE is reentered by either ChipSelectNot-TimeOut (CSNTO) or SW-Reset (in
both cases LHOME-bit is automatically reset) or setting this bit to ‘0’ via SPI access.
To stay in normal mode a rising edge has to be generated at CSN within every timeframe
programmed in the control register (Addr.: hex00, Bit 3,2). Else a CSNTO is detected and
FAIL SAVE entered.
When SDI is stuck to GND the device enters automatically FAIL SAVE.
When SDI is stuck to logical high level then the device receives a SW-Reset and enters FAIL
SAVE. A read of ROM address Addr.: hex3F is detected as stuck to logical high level.
In FAIL SAVE the SYNC pin is logical high.
