The reset value of the shaded bits is user specified, but the bits can be written after
reset to change the base address. If the values of ROMBAH bits ADDR[23:20] do not
match that of ADDR19, the CPU16 cannot access the ROM array.
ROMBAH and ROMBAL specify the 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 MC68HC16Z2 and the MC68HC16Z3 must be mapped to an 8-
Kbyte boundary, ROMBAL bits [12:0] always contain $0000. ROMBAH ADDR[15:8]
read zero.
Signature registers RSIGHI and RSIGLO contain a user-specified mask-programmed
signature pattern. A user-specified signature algorithm provides the capability to verify
ROM array contents.
