7 / 33 page 7 TABLE 4. SERIAL EEPROM PORT CONNECTIONS PIN NAME PIN NUMBER PIN I/O TYPE DESCRIPTION PJ0 P5 CMOS BiDir, 2mA, 50K Pull Up SCLK, serial clock for serial EEPROM devices PJ1 T1 CMOS BiDir, 2mA, 50K Pull Down Serial Data Out (SD) used on serial EEPROM devices which require three and four wire interfaces, example: AT45DB011 PJ2 R3 CMOS BiDir, 2mA, 50K Pull Down Serial Data In (MISO) used on serial EEPROM devices, Used in four wire serial devices only. Not currently supported in software. Consult the factory for additional updates on this option. TCLKIN(CS) L4 I/O, 50K Pull Down CS used for Chip Select Output for Serial Devices which have a 4 wire interface like the AST45DB011 and also serial data on two wire devices like the 24C08. TABLE 5.
