Serial Programming Data Input
NOTES:
1. If devices are configured for Direct operation of the PAFn/PAEn flag busses the FXI/EXI of the MASTER device should be tied LOW. All other devices tied HIGH. The FXO/EXO
2. Q outputs must not be mixed between devices, i.e. Q0 of device 1 must connect to Q0 of device 2, etc.
