Hi,
Please help me understand
what my options are with hooking up an SPI device.
the lpc2378 has an SPI Block
and an SSP block.
Is it true that the SPI block is unusable because the MOSI pin is used as a button2 input?
If so, then I have to utilize the SSP block.
But it appears that SSP0 goes to the LCD.
Which leaves me SSP1
So, is it correct to say my only option for hooking up an SPI device is to use SSP1?
And if so, I don't get the benefit of the interrupt for status and mode fault that comes with the SPI block?
Please help clear me up.

Thanks very much,
