Define Documentation

#define DFCMD_CONT_READ_LF 0x03

Continuos read (low frequency).

Reads a continous stream in low speed mode. Automatically switches to the the page and wraps to the first page after the last has been read. Note, that the data buffers are not used for this operation.

#define DFCMD_CONT_READ_HF 0x0B

Continuos read (high frequency).

Reads a continous stream in high speed mode. Automatically switches to the the page and wraps to the first page after the last has been read. Note, that the data buffers are not used for this operation.

#define DFCMD_BLOCK_ERASE 0x50

Block erase.

#define DFCMD_SECTOR_ERASE 0x7C

Sector erase.

#define DFCMD_PAGE_ERASE 0x81

Page erase.

Referenced by SpiAt45dPageErase().

#define DFCMD_BUF1_PROG 0x82

Main memory page program through buffer 1.

#define DFCMD_BUF1_FLASH 0x83

Buffer 1 flash with page erase.

Referenced by SpiAt45dPageWrite().

#define DFCMD_BUF1_WRITE 0x84

Buffer 1 write.

Referenced by SpiAt45dPageWrite().

#define DFCMD_BUF2_PROG 0x85

Main memory page program through buffer 2.

#define DFCMD_BUF2_FLASH 0x86

Buffer 2 flash with page erase.

#define DFCMD_BUF2_WRITE 0x87

Buffer 2 write.

#define DFCMD_BUF1_FLASH_NE 0x88

Buffer 1 flash without page erase.

#define DFCMD_BUF2_FLASH_NE 0x89

#define DFCMD_CHIP_ERASE 0xC7

Chip erase.

#define DFCMD_BUF1_READ_LF 0xD1

Buffer 1 read (low frequency).

#define DFCMD_READ_PAGE 0xD2

Read main memory page.

Automatically wraps to the first byte of the same page after the last byte had been read. The data buffers are left unchanged.

#define DFCMD_BUF2_READ_LF 0xD3

Buffer 2 read (low frequency).

#define DFCMD_BUF1_READ 0xD4

Buffer 1 read.

Read status register.

Referenced by At45dNodeStatus().

#define DFCMD_CONT_READ 0xE8

Continuos read (legacy).

Reads a continous stream. Automatically switches to the the page and wraps to the first page after the last has been read. Note, that the data buffers are not used for this operation.

Referenced by SpiAt45dPageRead().

#define AT45D_STATUS_RDY 0x80

Ready (not busy) flag.

#define AT45D_STATUS_COMP 0x40

Last compare result.
