Hello,
Maybe this can help you on the way. I have no part in Nogatech or Philips,
but stumbled on some
info locking for some other chip's.
If you get the pdf file from nogatech (nt1031DS.pdf (yes its for the nt1003))
and the SAA7111A from
philips you can see the following.
To set the serial interface in the nt1003 you have to set register 7
(SER_MODE). Set d7-d4 to 2 for
IICC (last byte read ack) as the SAA7111A sends ack last on read. d0-d3 to 4
will be ok.
Register 8 SER_ADRS is the adress read write ( 49H, 48H for SAA (i suppose))
and then you have
register 9 SER_CONT d0-d2 (numbers of byte (1-4)) and register 10 - 13 is the
byte read or write.
I think there will be some usefull info in this datasheet's for you.
God luck, and keep on coding.
Best regards.
