17.2.4 UROM_moveDP1
Notes:
• Before calling this function, DPC should be set appropriately to configure DP[1] 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.
