The MC68HC05C4A has an 8-Kbyte memory map, consisting of user
read-only memory (ROM), user random-access memory (RAM), self-
check ROM, and input/output (I/O) registers. See
Figure
The user ROM consists of 48 bytes of page zero ROM from $0020 to
$004F, 4096 bytes of ROM from $0100 to $10FF, and 16 bytes of user
vectors from $1FF0 to $1FFF. The self-check ROM and vectors are
located from $1F00 to $1FEF. See
Twelve of the user vectors, $1FF4 through $1FFF, are dedicated to
user-defined reset and interrupt vectors. The remaining four bytes from
$1FF0-$1FF3 are not used.
