Three different values:
RXI = 1: Contents of SSC Receive Buffer Register.
ERI = 1: Contents of SSC Control Register.
TXI = 1: 0000_H
SSC_IV(31 : 0) = A0010000_H
SSC_IV(31:16) = A004_H
SSC_IV(15:0): contents of SSC Control Register SSCCON
SSC_IV(31:16) = A002_H
SSC_IV(15:0): contents of SSC Rx Buffer Register SSCRB
