The value selected automatically may not always be correct for the device you are trying to write to This value may vary among different manufacturers Check the data sheet for your specific EEPROM if you think there may be a problem with performing page writes If the default parameter needs to be changed select the correct value from the pull down combo menu and select ok The maximum size allowed currently is 32 bytes Some devices are designed to use 64 byte write buffers but the TMS 120 is currently limited to 32 bytes at this time Choosing a buffer size smaller than the maximum buffer allowed for the device selected is ok but it will take more time to write data to the entire device 3 3 6 Address Pins 0 1 and A2 24C Series Only Some EEPROM devices have three pins labeled 0 Al and A2 These pins are used to modify the address that the chip will respond to thus allowing up to eight EEPROM devices to exist the same I C bus The EEPROM Tool software can be configured to work with any address configuration by clicking on the appropriate check boxes on the configuration dialog box This control is enabled only when a 24C series device has been selected Do not check the AO Al or A2 box unless you are sure that the device that you want to read or write has that pin tied to Vcc Check the schematic diagram of the circuit to see if the address pins are used 3 3 7 Organization 93C Series Only Most M
