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 (a6 a5 a4 A3 A2 A1 A0) determined by replacing the

low-order 4 bits of address a with register A in page p.

Returns from interrupt service routine to main routine.

Returns each value of data pointer (X, Y), carry flag, skip status, NOP mode status by the continuous

description of the LA/LXY instruction 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 at uncondition.

Clears (0) to the interrupt enable flag INTE, and disables the interrupt.

Sets (1) to the interrupt enable flag INTE, and enables the interrupt.

Skips the next instruction when the contents of EXF0 flag is “1.”

After skipping, clears the EXF0 flag.
