Bits 7 to 0: Receive Channels 1 to 32 Code Insertion Control Bits (CH[1:32])
0 = No clock is present on RCHCLKn during this channel time.
1 = Force a clock on RCHCLKn during this channel time. The clock will be synchronous with RCLKn if the
elastic store is disabled, and synchronous with RSYSCLKn if the elastic store is enabled.
When 2.048MHz backplane mode is selected, this register allows the user to enable the gapped clock on
RCHCLKn for any of the 32 possible backplane channels.
When 1.544MHz backplane mode is selected, the LSB of this register determines whether or not a clock is
generated on RCHCLKn during the F-bit time:
In this mode RGCCS4.1 to RGCCS4.7 should be set to 0.
0 = Do not insert data from the Idle Code Array into the receive data stream.
1 = Insert data from the Idle Code Array into the receive data stream.

RGCCS4.0 = 0, do not generate a clock during the F-bit.
RGCCS4.0 = 1, generate a clock during the F-bit.
