LDM – Load Multiple Registers
Architecture revision:
Architecture revision1 and higher.
Description
Loads the consecutive words pointed to by Rp into the registers specified in the instruction. The
PC can be loaded, resulting in a jump to the loaded target address. If PC is loaded, the return
value in R12 is tested and the flags are updated. The return value may optionally be set to -1, 0
or 1.
Operation:
I.
Loadaddress ← Rp;
if Reglist16[PC] == 1 then
else
for (i = 11 to 0)
if Opcode[++] == 1 then
if Rp == PC then
PC ← *(Loadaddress++);
