Internal RAM Map Position — These bits determine the upper five bits of the base address for the system’s
internal RAM array.
RAM High-Align — RAMHAL specifies the alignment of the internal RAM array.
0 Aligns the RAM to the lowest address (0x0000) of the mappable space
1 Aligns the RAM to the higher address (0xFFFF) of the mappable space
Writes to this register take one cycle to go into effect.
