Bits 7 to 0: Per-Channel Loopback Enable for Channels 1 to 32 (CH[1:32])

0 = no clock is present on TCHCLK during this channel time
1 = force a clock on TCHCLK during this channel time. The clock will be synchronous with TCLKn if the
elastic store is disabled, and synchronous with TSYSCLKn if the elastic store is enabled.
When 2.048MHz backplane mode is selected, this register allows the user to enable the gapped clock on
TCHCLK 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 TCHCLK during the F-bit time:
In this mode TGCCS4.1 to TGCCS4.7 should be set to 0.
0 = Loopback disabled.
1 = Enable loopback. Source data from the corresponding receive channel.

TGCCS4.0 = 0, do not generate a clock during the F-bit.
TGCCS4.0 = 1, generate a clock during the F-bit.
