Sa8 Bit Select.
Set to one to have RLCLK pulse at the Sa8 bit
position; set to zero to force RLCLK low during Sa8 bit
position. See Section 18 for timing details.
Sa7 Bit Select.
Set to one to have RLCLK pulse at the Sa7 bit
position; set to zero to force RLCLK low during Sa7 bit
position. See Section 18 for timing details.
Sa6 Bit Select.
Set to one to have RLCLK pulse at the Sa6 bit
position; set to zero to force RLCLK low during Sa6 bit
position. See Section 18 for timing details.
Sa5 Bit Select.
Set to one to have RLCLK pulse at the Sa5 bit
position; set to zero to force RLCLK low during Sa5 bit
position. See Section 18 for timing details.
Sa4 Bit Select.
Set to one to have RLCLK pulse at the Sa4 bit
position; set to zero to force RLCLK low during Sa4 bit
position. See Section 18 for timing details.
Receive Side Backplane Clock Select.
0 = if RSYSCLK is 1.544 MHz
1 = if RSYSCLK is 2.048 MHz
Receive Side Elastic Store Enable.
0 = elastic store is bypassed
1 = elastic store is enabled
Not Assigned.
Should be set to zero when written.
