Library Functions
FLASH_ERASE(), FLASH_READ()
Synopsis
Description
These functions allow access to the flash memory of the microcontroller (if supported).
function. flash_read() returns the data value found at the specified word address in flash memory.
flash_erase() function. Specifying an address to the flash_erase() function, will erase all 32 words
in the sector that contains the given address.
Example
Return Value
flash_read() returns the data found at the given address, as an unsigned int.
Reading from the flash memory can be done one word at a time with use of the flash_read()
Entire sectors of 32 words can be restored to an unprogrammed state (value=FF) with use of the
#include <htc.h>
void flash_erase (unsigned short addr);
unsigned int flash_read (unsigned short addr);
#include <htc.h>
void
main (void)
{
}
unsigned int data;
unsigned short address=0x1000;
data = flash_read(address);
flash_erase(address);
