Table 25. Address 0x18, STATUS Field Descriptions
Bit Field Type Reset Description
15:14 ERR_CHAN R 00 Error Channel
Indicates which channel has generated a Flag or Error. Once
flagged, any reported error is latched and maintained until either
the STATUS register or the DATAx_MSB register corresponding
to the Error Channel is read.
b00: Channel 0 is source of flag or error.
b01: Channel 1 is source of flag or error.
b10: Channel 2 is source of flag or error (LDC1614 only).
b11: Channel 3 is source of flag or error (LDC1614 only).
13 ERR_UR R 0 Conversion Under-range Error
b0: No Conversion Under-range error was recorded since the
last read of the STATUS register.
b1: An active channel has generated a Conversion Under-range
error. Refer to STATUS.ERR_CHAN field to determine which
channel is the source of this error.
12 ERR_OR R 0 Conversion Over-range Error
b0: No Conversion Over-range error was recorded since the last
read of the STATUS register.
b1: An active channel has generated a Conversion Over-range
error. Refer to STATUS.ERR_CHAN field to determine which
channel is the source of this error.
