SaX[1:4]:
Reading these bits returns the SaX nibble code word extracted from the sub-
multiframe., where ‘X’ corresponds to the National bit selected by the
SaSEL[2:0] bits in the National Bit Codeword Interrupt Enables register.
SaX[1] is from the first SaX bit of the sub-multiframe; SaX[4] is from the last.
A change in these bit values sets the SaI[X] bit of the International
Bits/National Interrupt Status register..
