Serial Interface Signals
• EE_DO (Output, 8 mA, Tri-State)
Master Mode: EEPROM data out Serial data, valid during EE_SK
edge. In master mode, this signal is an output.
Slave Mode: In slave mode, this signal is an output.
• EE_SK (I/O, 8 mA)
Master Mode: EEPROM data clock. This signal is an output in master
mode. It is active during R/W cycle only.
Slave Mode: In slave mode, this signal is an input.
• EE_CS (I/O, 8 mA)
Master Mode: EEPROM data chip select. This signal is an output in
master mode.
Slave Mode: In slave mode this signal is an input. This signal is active
High.
• EE_DI (Input, 100K Pull-Up)
Master Mode: EEPROM data in. This signal is an input in master
mode.
Slave Mode: In slave mode, this signal is an input.
• EE_MASTER (Input, Schmitt-Triggered, 100K Pull-Up)
Master/Slave mode detect: When set Low, no EEPROM is present.
When set High EEPROM is present.
