SFR Definition 12.1.
The XRAM Page Select Bits provide the high byte of the 16-bit external data memory
address when using an 8-bit MOVX command, effectively selecting a 256-byte page of
RAM. The upper 5-bits are "don't cares", so the 2k address blocks are repeated modulo over
the entire 64k external data memory address space.
