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 MC68376 must be mapped to an 8-Kbyte boundary, ROMBAL bits
[12:0] always contains $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.
