8.5.2 ERARNGE
ERARNGE is used to erase a range of locations in FLASH.
There are two sizes of erase ranges: a page or the entire array. The ERARNGE will erase the page (512
consecutive bytes) in FLASH specified by the address ADDRH:ADDRL. This address can be any address
within the page. Calling ERARNGE with ADDRH:ADDRL equal to $FFFF will erase the entire FLASH
array (mass erase). Therefore, care must be taken when calling this routine to prevent an accidental mass
erase.
The ERARNGE routine do not use a data array. The DATASIZE byte is a dummy byte that is also not
used.
The coding example below is to perform a page erase, from $EE00–$EFFF. The Initialization subroutine
is the same as the coding example for PRGRNGE (see
