headers ++ * ++ * Description: ++ * This file contains the structure definitions and manifest ++ * constants for ARM IP component: ++ * General Purpose Input/Output PrimeCell PL060 ++ * ++ * Each GPIO Module has two GPIO (digital IO) ports which are ++ * designated PORTA and PORTB. ++ * ++ * Multiple instances of a GPIO module, and thus port pairs, ++ * may be implemented in a single SOC. ++ * ++ * Each port has eight bits, PORTx[7:0]. ++ * ++ * Each port has two 8-bit registers associated with it: ++ * GPIOPxDR - Data register (dr) ++ * GPIOPxDDR - Data Direction register (ddr) ++ * ++ * The specific SOC will have its own unique name for the port. ++ * Each port pair will have its own unique base address for the ++ * port pair. ++ * ++ * This include file is designed to permit the definition of ++ * pointers in the SOC map include file to distinct 8-bit ports ++ * using the name designation is suitable for the SOC ++ * implementation. ++ * ++ * Example: ++ * A map file that includes this file should specify a ++ * base address for each GPIO module, e.g.: ++ * ++ * #define GPIO0_BASE (0xFFFDF000) ++ * #define GPIO1_BASE (0xFFFDE000) ++ * * ++ * * ++ * * ++ * ++ * The SOC map file will use these base addresses to define ++ * pointers to GPIO port A, B, C, D, E, ... thusly: ++ * ++ * #define GPIOPA ((volatile GPIOAREGS *)(GPIO0_BASE)) ++ * #define GPIOPB ((volatile GPIOBREGS *)(GPIO0_BASE)) ++ * #define GPIOPC ((volatile GPIOAREGS *)(GPIO1_BASE)) ++ * #define GPIOPD ((volatile GPIOBREGS *)(GPIO1_BASE)) ++ * #define GPIOPE ((volatile GPIOAREGS *)(GPIO2_BASE)) ++ * * ++ * * ++ * * ++ * ++ * Example usage of these definitions in user code for Port C: ++ * ++ * unsigned int data; ++ * ++ * GPIOC->ddr = 0xF; sets bits [7:4] as outputs ++ * and bits [3:0] as inputs ++ * GPIOC->dr = 0xF0; sets bits [7:4] to "1" ++ * ++ * data = GPIOC->dr; sets data to the value of ++ * data register ++ * ++ * Note: If it is desired to use the type qualifier "__packed" ++ * to enable packing of structures, the manifest constant ++ * "PACKED" must be defined as follows or as a ++ * predefine at compilation (ARM-specific notation): ++ * ++ * #define PACKED __packed ++ * ++ * If a different compiler/preprocessor is used, the appropriate ++ * notation must be substituted for "__packed". ++ * ++ * Reference: ARM PrimeCell General Purpose Input/Output (PL060) ++ * Technical
