Skip unconditionally
–
Branch within a page : Branches to address a in the identical page.
Branch out of a page : Branches to address a in page p.
Branch out of a page : Branches to address (DR2 DR1 DR0 A3 A2 A1 A0)2 specified by registers D and
A in page p.
Call the subroutine in page 2 : Calls the subroutine at address a in page 2.
Call the subroutine : Calls the subroutine at address a in page p.
Call the subroutine : Calls the subroutine at address (DR2 DR1 DR0 A3 A2 A1 A0)2 specified by registers
D and A in page p.
Returns from interrupt service routine to main routine.
Returns each value of data pointer (X, Y, Z), carry flag, skip status, NOP mode status by the continuous
description of the LA/LXY instruction, register A and register B to the states just before interrupt.
Returns from subroutine to the routine called the subroutine.
Returns from subroutine to the routine called the subroutine, and skips the next instruction unconditionally.
