Monitor ROM (MON)
10.6.3 LDRNGE
Technical Data
176
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
$EF00 in FLASH. The Initialization subroutine is the same as the coding
example for PRGRNGE (see
