Functions
int8_t	at45db_init (void)
	Initialize the AT45DBxx1 Flash EEPROM. More...

void	at45db_erase_chip (void)
	This function erases the whole chip. More...

void	at45db_erase_block (uint16_t addr)
	This function erases one block (4 Kbytes) More...

void	at45db_erase_page (uint16_t addr)
	This function erases one page e.g. More...

void	at45db_write_buffer (uint16_t addr, uint8_t *buffer, uint16_t bytes)
	This function writes bytes to the active buffer, while the buffer management is done automatically. More...

void	at45db_buffer_to_page (uint16_t addr)
	This function copies the active buffer into the Flash EEPROM page. More...

void	at45db_write_page (uint16_t p_addr, uint16_t b_addr, uint8_t *buffer, uint16_t bytes)
	This function copies the data from the the pointer into the buffer, erases the EEPROM page and flashes the new content directly into the page. More...

void	at45db_read_page_buffered (uint16_t p_addr, uint16_t b_addr, uint8_t *buffer, uint16_t bytes)
	Bytes can be read via buffer from a Flash EEPROM page. More...

void	at45db_read_page_bypassed (uint16_t p_addr, uint16_t b_addr, uint8_t *buffer, uint16_t bytes)
	Bytes can be read direct (bypassed) from a Flash EEPROM page. More...

void	at45db_page_to_buf (uint16_t addr)
	Copies the given page into the buffer 2. More...

void	at45db_read_buffer (uint16_t b_addr, uint8_t *buffer, uint16_t bytes)
	This function readouts the buffer 2 data. More...

void	at45db_write_cmd (uint8_t *cmd)
	The command word of the AT45DBxx1 normally consists of 4 bytes. More...

void	at45db_busy_wait (void)
	This function waits until the busy flag of the status register is set, to detect when the AT45DBxx1 device is ready to receive new commands.
