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.
