Using lpc1227 SPI in master mode, lpc1227 sends out clock pulses correctly, but the data bits are sent out on MISO pin. I initialized the pin as an input pin. As soon as I enable the SPI master mode, the data bits are sent at thisMISO pin!!!
What did I do wrong?

I apologized.
I mislabeled the MISO and MOSI lines.
The lpc1227 SPI master mode is working fine.
This post should be deleted.

My question is:
Why does lpc1227 SPI master mode send data out at SSP-MISO?
