PAGE n - The three literal bits of "n" are loaded into the page-select bits PA2:PA0 in the STATUS register. This normally prepares a GOTO or CALL across a page boundary. PA2 is currently unused since 2K of instruction memory is only four pages.
Skipping a page instruction will also cause the instruction following the page instruction to be skipped. This is designed to handle long calls which must be coded as a page then a call. See Skip for more details.
