ureg DM|PM (direct addressing)
Syntax:
a. DM(<addr32>)
PM(<addr24>)
b. ureg = DM(<addr32>)
Function:
Access between data memory or program memory and a universal
register, with direct addressing. The entire data memory or program
memory address is specified in the instruction. Data memory addresses
are 32 bits wide (0 to 2
24
(0 to 2 –1).
Examples:
DM(temp)=MODE1;
DMWAIT=PM(0x489060);

D selects the access type (read or write). G selects the memory type (data
or program). UREG specifies the number of a universal register. ADDR
contains the immediate address value.
