It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the value bit that specifies the value that will be written into the selected bits of register. eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered. */ /* Offset for Memory Mapped Registers. */ /* 32 bit registers */ #define ASF_STAT 0x00 /* ASF status register */ #define CHIPID 0x04 /* Chip ID regsiter */ #define MIB_DATA 0x10 /* MIB data register */ #define MIB_ADDR 0x14 /* MIB address register */ #define STAT0 0x30 /* Status0 register */ #define INT0 0x38 /* Interrupt0 register */ #define INTEN0 0x40 /* Interrupt0 enable register*/ #define CMD0 0x48 /* Command0 register */ #define CMD2 0x50 /* Command2 register */ #define CMD3 0x54 /* Command3 resiter */ #define CMD7 0x64 /* Command7 register */ #define CTRL1 0x6C /* Control1 register */ #define CTRL2 0x70 /* Control2 register */ #define XMT_RING_LIMIT 0x7C /* Transmit ring limit register */ #define AUTOPOLL0 0x88 /* Auto-poll0 register */ #define AUTOPOLL1 0x8A /* Auto-poll1 register */ #define AUTOPOLL2 0x8C /* Auto-poll2 register */ #define AUTOPOLL3 0x8E /* Auto-poll3 register */ #define AUTOPOLL4 0x90 /* Auto-poll4 register */ #define AUTOPOLL5 0x92 /* Auto-poll5 register */ #define AP_VALUE 0x98 /* Auto-poll value register */ #define DLY_INT_A 0xA8 /* Group A delayed interrupt register */ #define DLY_INT_B 0xAC /* Group B delayed interrupt register */ #define FLOW_CONTROL 0xC8 /* Flow control register */ #define PHY_ACCESS 0xD0 /* PHY access register */ #define STVAL 0xD8 /* Software timer value register */ #define XMT_RING_BASE_ADDR0 0x100 /* Transmit ring0 base addr register */ #define XMT_RING_BASE_ADDR1 0x108 /* Transmit ring1 base addr register */ #define XMT_RING_BASE_ADDR2 0x110 /* Transmit ring2 base addr register */ #define XMT_RING_BASE_ADDR3 0x118 /* Transmit ring2 base addr register */ #define RCV_RING_BASE_ADDR0 0x120 /* Transmit ring0 base addr register */ #define PMAT0 0x190 /* OnNow pattern register0 */ #define PMAT1 0x194 /* OnNow pattern register1 */ /* 16bit registers */ #define XMT_RING_LEN0 0x140 /* Transmit Ring0 length register */ #define XMT_RING_LEN1 0x144 /* Transmit Ring1 length register */ #define XMT_RING_LEN2 0x148 /* Transmit Ring2 length register */ #define XMT_RING_LEN3 0x14C /* Transmit Ring3 length register */ #define RCV_RING_LEN0 0x150 /* Receive Ring0 length register */ #define SRAM_SIZE 0x178 /* SRAM size register */ #define SRAM_BOUNDARY 0x17A /* SRAM boundary register */ /* 48bit register */ #define PADR 0x160 /* Physical address register */ #define IFS1 0x18C /* Inter-frame spacing Part1 register */ #define IFS 0x18D /* Inter-frame spacing register */ #define IPG 0x18E /* Inter-frame gap register */ /* 64bit register */ #define LADRF 0x168 /* Logical address filter register */ /* Register Bit Definitions */ typedef enum { ASF_INIT_DONE = (1 << 1), ASF_INIT_PRESENT = (1 << 0), }STAT_ASF_BITS;
