Hi,
I am working on XMC 4100. I have interfaced ST M95320 (SPI EEPROM) to XMC 4100 through SPI communication. I have certain doubts which need to be cleared.
1-> In ST M 95320 DataSheet it is clearly mentioned that EEPROM will work only in MODE 0 or MODE 3 but for me EEPROM is working in MODE 1(Phase 0 Polarity 1)only.
2-> It's working fine at 100kbps baud rate only if I am increasing the baud rate the EEPROM Write and Read operation are not successful.

If anybody here worked on SPI EERPOM please do clear this doubts.


Thanks,
Irfan
