The FPGA clocks from the AVR are effected differently in the various sleep modes of the AVR,
see
The source clock into the FPGA GCK5 and GCK6 will determine what happens during the vari-
ous power-down modes of the AVR.
If the XTAL clock input is used as an FPGA clock (GCK5 or GCK6) in Idle mode, it will still be
running. In Power-down/save mode the XTAL clock input will be off.
If the TOSC clock input is used as an FPGA clock (GCK6) in Idle mode, it will still be running in
Power-save mode but will be off in Power-down mode.
If the Watchdog Timer is used as an FPGA clock (GCK6) and was enabled in the AVR, it will be
running in all sleep modes.
