AVR32
POPM – Pop Multiple Registers from Stack
Architecture revision:
Architecture revision1 and higher.
Description
Loads the consecutive words pointed to by SP into the registers specified in the instruction. The
PC can be loaded, resulting in a jump to the loaded value. If PC is popped, the return value in
R12 is tested and the flags are updated. R12 can optionally be updated with -1, 0 or 1. The k bit
in the instruction coding is used to optionally let the POPM instruction update the return register
R12 with the values -1, 0 or 1.
Operation:
I.
