This register determines the position of the 256 Byte direct page within the memory map.It is valid for both
global and local mapping scheme.
Bits [22:16] of the global address will be formed by the GPAGE[6:0] bits in case the CPU executes a global
instruction in direct addressing mode or by the appropriate local address to the global address expansion
