// Project Code : PAYPASS LIBRARY
// Project Name : PAYPASS LIBRARY
// Module Name  : LPC2103_PAYPASS_TTAL1_FUNCTIONS.H
// Platform dev : Keil 礦ision 3 (IDE ) + Keil ARM Compiler
// Target       : LPC2103 (ARM7TDMI Core) MCB2103 Vers.1
// Language     : C ANSI
// Revision     : 1.2
// Description  : Special functions requiring to be modified according to the target and the user needs (i.e Choice of IO for the SPI)
//				  also SDO_MASK SDI_MASK SCK_MASK and CS_MASK must be modified according to 
//                IOs choosen for SPI communication
