5.1
The source of every of the eight receive clocks (RCLK(8:1)) can be independently
selected out of every of the eight channels. The additional registers GPC2 to GPC6 are
used for controlling. GPC2 to GPC6 are not valid if COMP = ´1´. For COMP = ´1´ only
the source of RCLK1 can be selected by the register GPC1 of the pseudo QuadFALC
RCLK2,3,4 sources are the appropriate channels. Equivalent, the RCLK5 source can be
selected by the register GPC1 of the pseudo QuadFALC
RCLK6,7,8 are the appropriate channels. For the principle see also
reset RCLK1 is sourced by channel 1 and RCLK5 is sourced by channel 5 and switched
to the multi function ports RPC.
Note that in CT mode the DCO-R is always on.

The transmit clock can be automatically switched between TCLK and SCLKX. This
enables an automatic switch over between different clock sources within the system in
case the original clock source is lost. In general the clock switching is glitch free.
