Chip Enable
This pin is designed to directly interface to a serial
EEPROM that use the 93C66 EEPROM interface proto-
col. This pin has to be connected directly to the
EEPROM’s chip select pin.
Serial Clock or General Purpose Output Pin 6 depending
on the internal selection. The selection is performed writ-
ing the proper bit inside the PCFW or UCFW register. At
the power-on or hardware reset the CFG_CLK functional-
ity is selected. This pin is designed to directly interface to
a serial EEPROM that use the 93C66 EEPROM interface
protocol.
Serial Data Input
Data going into this pin has to be generated on the rising
edge of CFG_SCK. This pin is designed to directly inter-
face to a serial EEPROM that use the 93C66 EEPROM
interface protocol.
Serial Data/Address Output
General Purpose Output Pin 7 depending on the internal
selection. The selection is performed writing the proper bit
inside the PCFW or UCFW register. At the power-up or
hardware reset the CFG_SDO functionality is selected.
The CFG_SDO data change is synchronous with the fall-
ing edge of CFG_SCK. This pin is designed to directly
interface to a serial EEPROM that use the 93C66
EEPROM interface protocol.
