| * POPX.A | Restore single address-word from the stack | ||
| * POPX.[W] | Restore single word from the stack | ||
| * POPX.B | Restore single byte from the stack | ||
| Syntax | POPX.A dst | ||
| POPX dst or POPX.W dst | |||
| POPX.B dst | |||
| Operation | Restore the 8-, 16-, 20-bit value from the stack to the destination. 20-bit addresses are possible. The SP is incremented by 2 (byte and word operands) and by 4 (address-word operand). | ||
| Emulation | MOVX(.B,.A) @SP+,dst | ||
| Description | The item on TOS is written to the destination operand. Register mode, indexed mode, symbolic mode, and absolute mode are possible. The SP is incremented by 2 or 4. | ||
| Note: the SP is incremented by 2 also for byte operations. | |||
| Status Bits | Status bits are not affected. | ||
| Mode Bits | OSCOFF, CPUOFF, and GIE are not affected. | ||
| Example | Write the 16-bit value on TOS to the 20-bit address &EDE | ||
POPX.W &EDE ; Write word to address EDE
| Example | Write the 20-bit value on TOS to R9 | ||
POPX.A R9 ; Write address-word to R9
