7EIN_STATUSR/W00 = All values added to the EIN accumulator match the setting of EIN_ACCUM
1 = The EIN accumulator encountered a value inconsistent with the selected mode of operation. For EIN_ACCUM = 01, a negative value of the sign bit of READ_IIN is detected. For EIN_ACCUM = 10, a positive value of the sign bit of READ_IIN is detected. EIN_STATUS is not set when EIN_ACCUM is 00 or 11.

5:4EIN_ACCUMR/W0000, 11 = The READ_EIN accumulator sums all values of the READ_POUT register. Both negative and currents increase the accumulator.
01 = The READ_EIN only sums positive values of the READ_POUT register based on the sign bit of the READ_IIN register; the sample count continues to increment for negative values
10 = The READ_EIN only sums negative values of the READ_POUT register based on the sign bit of the READ_IIN register; the sample count continues to increment for positive values
