DESCRIPTION
Transmit A Bit:
This READ/WRITE bit-field permits the user to control the state
of the "A" bit, within each "outbound" E3 frame, as indicated
below.
0 - Forces each A bit (within the "outbound" E3 frame) to "0".
1 - Forces each A bit (within the "outbound" E3 frame) to "1".
NOTE: This bit-field is only valid if the Frame Generator block
has been configured to use this bit-field as the source of
the "A" bit (e.g., if "TxASrcSel[1:0] = "0, 0").
Transmit N Bit:
This READ/WRITE bit-field permits the user to control the state
of the "N" bit, within each "outbound" E3 frame, as indicated
below.
0 - Forces each N bit (within the "outbound" E3 frame) to "0".
1 - Forces each N bit (within the "outbound" E3 frame) to "1".
NOTE: This bit-field is only valid if the Frame Generator block
has been configured to use this bit-field as the source of
the "N" bit (e.g., if "TxNSrcSel[1:0] = "0, 0").
