NOTE:
Address: $003D
Out of reset, the 128-byte register block is mapped to $0000 and the
768-byte RAM (1 Kbyte on the [7]11KS2) is mapped to $0080. Both the
register block and the RAM can be placed at any other 4-Kbyte boundary
($x000 and $x080, respectively) by writing the appropriate value to the
INIT register.
INIT is writable once in normal modes and writable at any time in special
modes.
