Monitor ROM (MON)
8.5.3 LDRNGE
LDRNGE is used to load the data array in RAM with data from a range of FLASH locations.
The start location of FLASH from where data is retrieved is specified by the address ADDRH:ADDRL and
the number of bytes from this location is specified by DATASIZE. The maximum number of bytes that can
be retrieved in one routine call is 255 bytes. The data retrieved from FLASH is loaded into the data array
in RAM. Previous data in the data array will be overwritten. User can use this routine to retrieve data from
FLASH that was previously programmed.
The coding example below is to retrieve 64 bytes of data starting from $EE00 in FLASH. The Initialization
subroutine is the same as the coding example for PRGRNGE (see
