15.2.13 The Jump Instruction
When a JMP instruction is executed, the lower nine bits of the program counter are loaded with the
address of the label specified. The upper two or three bits of the program counter are loaded with the
page select bits, PA2:PA0, from the STATUS register. Therefore, care must be used to ensure the page
select bits are pointing to the correct page before the jump occurs.
