Note:
SDI, SCLK, SCSZ are for 3-wire commands and should be connected to microcontroller I/O pins.
CLKA and FSY.
Typical application of default setting uses National single channel Combo (Quad Combo can be used to replace
the 4 single Combo)
When there are multiple AT2008 used on the same systems, A1, A0 are used to identify the chip.
A1, A0 are for chip ID. Values are from 00-03. They should be connected to microcontroller I/O lines or wired to either
VCC or ground.
