•

For slave mode—The user has two groups of five address pins each. The user decides

These three bits always relate

to FCC2 master

Pins

to an FCC1 master.

These two address bits relate to the

master of FCC1 or FCC2 according

to the programming. Bit 4 is the msb.

Pins

These 5 address bits relate to the

slave of FCC1 or FCC2 according to

the programming. Bit 4 is the msb.

NOTE: To use FCC2 as shown, connect the FCC2 address bits reversed with
