Maxim Integrated 17-7

17.2.10 UROM_moveBP

Notes:

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

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

in Figure 2-4 and Figure 2-5. When a byte mode address is used, CDA0 must be set appropriately to access either

the upper or lower half of program flash/ROM memory.

• This function automatically refreshes the data pointer before reading the byte/word value.

17.2.11 UROM_copyBuffer

Notes:

• 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 2-4 and Figure 2-5. When a byte mode address is used, CDA0 must be set appropriately to access either

the upper or lower half of program flash/ROM memory.

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