USER’S MANUAL

D.4.4 ROM Bootstrap Words

Typically, CPU16 reset vectors reside in non-volatile memory and are fetched when

the CPU16 comes out of reset. These four words can be used as reset vectors with

the contents specified at mask time. The content of these words cannot be changed.

On generic (blank ROM) MC68HC16Z2 and MC68HC16Z3 devices, ROMBS[0:3] are

masked to $0000. When the ROM on the MC68HC16Z2 and MC68HC16Z3 is masked

with customer specific code, ROMBS[0:3] respond to system addresses $00000 to

$00006 during the reset vector fetch if BOOT = 0.
