Good Day All,
I'm bringing up a project with LPC2294 Rev/01. This part owns the SSP
interface. To activate this, you first have to deactivate SPI1 in PCONP,
using Bit 10 P...

I'm trying to setup an SSP port as SPI to interface with a 4M SPI Flash
memory chip, eg. M25P40. For a MEM write cycle, you must send 8 bit
opcode, 24 bit adr, and 8 bit data....

You're right, I don't really need to read it twice. I didn't have the inn=
