Description
Power Supply
Ground
27 MHz clock output.
S0 is activated during power on for logic state strapping, then
switches to 27 MHz SSC clock output.
Crystal or reference clock input
X2/S1 is a multiple function pin. S1 is active during power on
selection of SSC spread then switches to crystal input.
