OVC
Overflow counter
Description
Store the 6 bits of the overflow counter (OVC) into the lower 6 bits of the
location pointed to by the “loc16” addressing mode and zero the upper 10
bits of the addressed location:
[loc16(15:6)] = 0;
[loc16(5:0)] = OVC;
Flags and
Modes
N
If (loc16 = @AX) and bit 15 of AX is 1, then set N; otherwise clear N.
Z
If (loc16 = @AX) and AX is zero, then set Z; otherwise clear Z.
Repeat
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; Save and restore contents of ACC and OVC bits:
MOVU *SP++,OVC
; Save OVC on stack
MOV *SP++,AL
; Save AL on stack
MOV *SP++,AH
; Save AH on stack
.
.
.
.
MOV AH,*−−SP
; Restore AH from stack
MOV AL,*−−SP
; Restore AL from stack
MOVU OVC,*−−SP
; Restore OVC from stack
