Hi all,

I have to send a command equence to the S6E63D6 SPI display controller 
(just google for it, the first non-sponsored link has a datasheet). But 
its write timing diagram made me wonder how to achieve it... It has 16-bit 
registers, and the timing diagram looks like

1. CS down
2. send 1 start byte
3. pause the clock, hold CS
4. send 2 bytes register address back-to-back
5. stop clock, CS up

similarly you send data. So, what makes me uncertain is this pattern - 1 
byte, pause, 2 bytes back-to-back. All three bytes while holding CS. I 
tried just sending a 3-byte buffer, doesn't seen to work at first. Is 
there a way to reproduce this with the current SPI API?

Thanks
Guennadi
