21.3.4 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 21-1. 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]
21.3.5 UROM�moveDP1inc
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 21-1. 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]++
21.3.6 UROM�moveDP1dec
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 21-1. 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]--
