Lpc2000

Hello friends,
           i am using LPC2214 as Master and LPC 2104 as slave in my 
project using KEIL UVISION3.The communication between these two 
controller through SPI.
 Iam using ISR s in both controllers.
 But my master SPI ISR is working fine ,if the slave SPI is in 
polling mode.If the slave SPI IRQ is enabled im unable to collect
the data in slave ISR  and master ISR.
So please,if somebody has any idea help me?
Thanking you,
sunil.
