25.3.4 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 25-1. 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.
