Setting up TRF-2.4G LAIPAC Transceiver using 8051

I’m trying to setup the LAIPAC TRF-2.4G transceiver as a receiver using a Cypress USB 8051 based development board. I’ve got sample code in AVR and PIC for setting up the transceiver from which I tried setting it up using the 8051. Unfortunately, it doesnt work once I ported it over to 8051.

Has anyone done this before who could help with this problem?
