21.3.10 UROM�copyBuffer

Notes:

• This function can be used to copy from program flash to data RAM, or from one part of data RAM to another. It can-

not be used to copy data into flash memory; the UROM_writeFlash function should be used for this purpose.

• Before calling this function, DPC should be set appropriately to configure DP[0] and BP[OFFS] for byte or word

mode. Both DP[0] and BP[OFFS] should be configured to the same mode (byte or word) for correct buffer copying.

• The addresses passed to this function should be based on the data memory mapping for the utility ROM, as shown

in Figure 21-1. When a byte mode address is used, CDA0 must be set appropriately to access either the upper or

lower half of program flash memory.

• This function automatically selects the data pointers before reading the byte/word values.

21.3.11 UROM�stopMode

Notes:

• Stop mode should normally be called from user code.
