Error Status Command.

PARITY: Indicates when the transmitted parity bit does not match to calculated parity bit

CLKMON: Clock monitoring indicates when the amount of clock cycles is not correct

ADDMON: Address monitoring appears when the address does not exist

WOW: This is a handshake mechanism to check system integrity. By sending a READ ANGLE command the internal flag (WOW) is set to high.

At the end of measurement the WOW is set to low again. In failure case (internal dead lock situation) the WOW flag remains high.

MODE: During sleep mode, the flag is 0. When the IC is busy (measuring), the flag is 1.

DACOV: The DACOV bit occurs if the magnetic input field strengths is too large for at least one Hall element. This can be the case if the magnet

is displaced.

DSPOV: CORDIC overflow occurs when the input signals of CORDIC are too large

RANERR: Range error appears when the voltage drop over the internal current source decreases which is caused by increased temperature.

The accuracy is getting worse.

DSPALO: DSP Alarm LO; AGC level is equal or even lower than the minimum level.

DSPAHI: DSP Alarm HI; AGC level is equal or even higher than the maximum level.

For additional information on Error Status, please refer to the application note AN5000_Error Monitoring.
