For 12 bit addressing, SA0:SA11 only, nCS should be tied to GND. For 16 bit external
address qualification, address bits SA11:SA15 can be "ORed" together and applied to nCS.
controls the FDC37M60x addressing modes.
The "n" as the first letter of a signal name indicates an "Active Low" signal.
KBDRST is active low.
The nCS pin functions as SA11 in full 16 bit Internal Address Qualification Mode. CR24.6
