Description
1 = enables the SED circuitry. None of the flags in this
register or the values in Register 0x70 through
Register 0x73 are significant if the SED is not enabled.
1 = indicates an error is detected. The bit remains set
until cleared. Any write to this register clears this bit to 0.
1 = enables autoclear mode. This activates Bit 1 and Bit
0 of this register and causes Register 0x70 through
Register 0x73 to be autocleared whenever eight
consecutive error-free sample data sets are received.
1 = indicates an error has been detected. This bit
remains high until it is autocleared by the reception of
eight consecutive error-free comparisons or until it is
cleared by writing to this register.
1 = indicates that the last sample comparison was error free.
Compare Value I0[15:0] is the word that is compared
with the I0 input sample captured at the input interface.
See Register 0x68.
Compare Value Q0[15:0] is the word that is compared
with the Q0 input sample captured at the input interface.
See Register 0x6A
Compare Value I1[15:0] is the word that is compared
with the I1 input sample captured at the input interface.
See Register 0x6C.
Compare Value Q1[15:0] is the word that is compared
with the Q1 input sample captured at the input interface.
See Register 0x6E.
Errors detected I_BITS[15:0] indicates which bits were
received in error.
See Register 0x70.
Errors detected Q_BITS[15:0] indicates which bits were
received in error.
See Register 0x72.
