Memory
There are two types of memory commands are available, Fill Memory and Read
Memory.
4.5.1
Fill Memory
The Fill Memory command allows the user to write to the memory location of the target
device with the desired data size in Little Endian format. The user will need to select the
desired data size (8 bits, 16 bits, or 32 bits), then enter the number of data size to fill
(4 digits decimal value), starting address (Hex value), and the pattern (Hex value) to be
written to the target address.
4.5.2
Read Memory
The Read Memory command allows the user to read to the desired memory location of
the target device in the Little Endian format. The user will need to select the data size to
be read (8 bits, 16 bits, or 32 bits), and then enter the starting address (Hex value) to
read from the target. The output displays a maximum of 8 address values (for 8 bytes or
4 words or 2 long words) of Hex value per line, and it displays from lower address to
higher address (left to right, and top to bottom). Please note that the available memory
address in the AT43DK370 Development Board ranges up to 0x3FFFFFFF. The user
will not be able to read or write to memory addresses beyond this limit.
