8.6.5 Register 4: Error Register (address = 04h) [reset = 0000 0000b]

The Error Register flags activate whenever an error condition is detected. These flags are cleared when a 1 is written to the error bit.

Bit Descriptions:

CHKerr: Checksum error in SPI. This bit is only active if checksum is enabled. This bit is set to 1 when the checksum byte is incorrect.

IARerr: Input Amplifier Saturation

BUFA: Buffer Active

ICAerr: Input Clamp Active

EF: Error Flag. Logic OR combination of error bits of Register 10. This bit can be connected to GPIO3 pin if the bit is configured for output (Register 8) and as a special function (Register 12).

OUTerr: Output Stage Error (allow approximately 6µs activation delay).

GAINerr: Gain Network Overload

IOerr: Input Overvoltage
