erase_program_eeprom( )
Syntax:
erase_program_eeprom ( address );
Parameters: address is 16 bits on PCM parts and 32 bits on PCH parts . The least significant
bits may be ignored.
Returns:
Function:
undefined
Erases FLASH_ERASE_SIZE bytes to 0xFFFF in program memory.
FLASH_ERASE_SIZE varies depending on the part. For example, if it is 64 bytes
then the least significant 6 bits of address is ignored.
See write_program_memory() for more information on program memory access.
Availability: Only devices that allow writes to program memory.
