2.2 Introduction
The MC68HC05C8A 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 2-1
and
Figure 2-2
.
2.3 Read-Only Memory (ROM)
The user ROM consists of 48 bytes of page zero ROM from $0020 to
$004F, 7680 bytes of user ROM from $0100 to $1EFF, and 16 bytes of
user vectors from $1FF0 to $1FFF. The self-check ROM and vectors are
located from $1F00 to $1FEF. See
Figure 2-1.
Twelve of the user vectors, $1FF4–$1FFF, are dedicated to user-
defined reset and interrupt vectors. The remaining four bytes from
$1FF0–$1FF3 are not used.
