Has anyone got this Epson RTC running with SPI?.
The RX6110SA I'm using does not go tristate on MISO during slave reception of byte.
Very difficult to understand the Jinglish application manual for this chip to establish the exact requirements for initialisation but as the MISO is not acting correctly, I suspect its a bad chip.
If anyone can confirm that they have actually run in SPI mode (SPISEL tied high) then its clearly a hardware issue.
Running it with the great little AT90USB1287.
