21.3.4UROM�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
. When a byte mode address is used, CDA0 must be set appropriately to access either the upper or
lower half of program flash memory .
• This function automatically selects DP[1] as the data pointer before reading the byte/word value .
• Implemented as: move GR, @DP[1]
