data areas (special function registers and internal RAM) can be selected. A LOCATION instruction must always be

executed after a reset, and can be used only once.

(1) When the LOCATION 0 instruction is executed

Internal data areas are mapped to 0F700H-0FFFFH.

(2) When the LOCATION 0FH instruction is executed

Internal data areas are mapped to FF700H-FFFFFH.
