24.3.1 UROM_moveDP0
Notes:
• Before calling this function, DPC should be set appropriately to configure DP[0] 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 24-1. 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.
