Is 4.7K okay for the pull-up of SDA/SCL I2C/SMBUS signals?
Do we need to pull pin 39 (SMBUSz/SS_SUSPEND) down to program the EEPROM? Right now, we are not using pin 39. The default is PU. Do we need to do anything with register 0xF0 (Advanced Configuration Register), which enables this mode?
This question relates to my other two questions on how to program the EEPROM. I would like to use the USB interface and the Windows applet. In order to do that, I need to enable programming mode, hence this question.
Enabling Programming Mode
There are three conditions that will enable programming mode:
1) A blank EEPROM is present and functional
2) An EEPROM is present in which address 0x00 = 0xFF
3) Programming mode has been externally enabled.
Forcing document: Step 4: Open the programming tool. Pullups must be installed on SDA and SCL to program an EEPROM.
