NAME AND DESCRIPTION
Sa8S
RCR2.7
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 13 for tim-
ing details.
Sa7S
RCR2.6
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 13 for tim-
ing details.
Sa6S
RCR2.5
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 13 for tim-
ing details.
Sa5S
RCR2.4
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 13 for tim-
ing details.
Sa4S
RCR2.3
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 13 for tim-
ing details.
RBCS
RCR2.2
Receive Side Backplane Clock Select.
0=if RSYSCLK is 1.544 MHz
1=if RSYSCLK is 2.048 MHz
RESE
RCR2.1
Receive Side Elastic Store Enable.
0=elastic store is bypassed
1=elastic store is enabled
