Hello,

I'm controlling a NHD-1.69-160128G (display controller SEPS525 ) via 4 wire-SPI ( no parallel interface ). I want to read back configuration settings via SPI. Is there SPI timing data available for with the 4 wire (SCL, SDI, SCL, RS) how to do this?

Rregards,
Frank

  Hi FrankT,
  
  Unfortunately the NHD-1.69-160128G display with the SEPS525 controller does not support Serial Data Out. 
  Currently our datasheet indicates that SDO is tied to DB[15] as it also shows in the SEPS525 controller spec.  However, that spec is conflicting itself as it also shows DB[15] is not connected as noted on page 9. 
  We will update the datasheet to help avoid this confusion.
