I have to problem with LPC1227

1) I am using the LPC1227FBD64 as a slave in a SPI communication.

The spi have all pin MISO, MOSI,SCK,SSEL.
The master mcu makes low the SSEL and then send a raw 30 bytes in spi and after makes high the SSEL.
I only get the first byte in first byte of the 30 bytes!! I tried to configure the LPC1227 with interrupt or no interrupt. The same problem
I tried to use the SPI in LPC1227 as a slave without the SSEL it does not work.

2) No external edge interrupt
I setup P0_15 to make edge interrupt it did not work . With level interrupt it worked


Does anyone have tried this?
