RESET:
1. Reset value of the shaded bits is user specified but the bits can be written after reset to change the base address.
ROMBAH and ROMBAL specify ROM array base address. The reset state of these
registers is specified at mask time. They can only be written when STOP = 1 and
LOCK = 0. This prevents accidental remapping of the array. Because the 8-Kbyte
ROM array in the MC68HC16Y3/916Y3 must be mapped to an 8-Kbyte boundary,
ROMBAL bits [12:0] always contain $0000. ROMBAH ADDR[15:8] read zero.
RSIGHI and RSIGLO specify a ROM signature pattern. A user-written signature iden-
tification algorithm allows identification of the ROM array content. The signature is
specified at mask time and cannot be changed.
If the values of ROMBAH bits ADDR[23:20] do not match that of ADDR19, however, the CPU16 cannot access
the ROM array.
