Valid when the FDIS (b3, E1-040H) is logic 0, and the INDIS (b1, E1-040H) is logic 0.
= 0: Disable the corresponding bit in the SaX[1:4] to replace the national bit codeword selected by the SaSEL[2:0].
= 1: Enable the corresponding bit in the SaX[1:4] to replace the national bit codeword selected by the SaSEL[2:0].
These bits are the codeword to be inserted into a CRC-4 Sub Multi-Frame.
The setting in the SaX[1:4] will replace the National bits which are assigned by the SaSEL[2:0].
If the code word is written during SMF I of a CRC-4 Multi-Frame, it will appear in the SaX[1:4] bits of SMF II of the same Multi-Frame. If the code

This bit is clear to ‘0’ after a rising and falling edge occur on the internal clock or after the register is read.
= 0: Disable the operation of the RHDLC block and all the FIFO buffer and interrupts are cleared.

No address matching is needed. All the HDLC data is stored in the FIFO.
The HDLC data is stored in the FIFO when the first byte is all ‘One’s or the same as the setting in the PA[7:0] (b7~0, E1-04CH) or
the SA[7:0] (b7~0, E1-04DH).
The HDLC data is stored in the FIFO when the most significant 6 bits in the first byte are all ‘One’s or the same as the setting in the
PA[7:2] (b7~2, E1-04CH)or the SA[7:2] (b7~2, E1-04DH).
