AR0H
Upper 16-bits of XAR1 and XAR0 auxiliary registers
Description
Predecrement SP by 2. Load the contents of AR0H with the value pointed to
by SP and AR1H with the value pointed to by SP+1. The lower 16 bits of the
auxiliary registers (AR0 and AR1) are left unchanged.
SP −= 2;
AR0H = [SP];
AR1H = [SP+1];
AR1:AR0 = unchanged;
Flags and
Modes
None
Repeat
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
