PushW (DW $048) |
|
| Description: | Push the contents of W onto the "Wstack" |
| Operation: | Wstack[WSP++] = W |
| Flags affected: | ? |
| Registers affected: | Wstack |
| Sources referenced: | W |
| Cycles: | 1 |
| Opcode: | $048 |
| Details: | Secret Instructions Page |
| Microchip PIC syntax: | n/a |
| Notes: | |
The Wstack is only two levels deep and is used by both the interrupt and the debug system. If you don't set a breakpoint or happen to break into debug while in an ISR, you can use one level without concern. If you don't use interrupts or debug, you can use both levels.
To use this instruction, first define the following macro.
PushW macro DW $048 endm
