Section 2. Memory
2.1 Contents
2.2 Introduction
The MC68HC05C12A has an 16-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
2.3 Read-Only Memory (ROM)
The user ROM consists of 48 bytes of page zero ROM from $0020 to
$004F, 12,032 bytes of user ROM from $1000 to $3EFF, and 16 bytes
of user vectors from $3FF0 to $3FFF. The self-check ROM and vectors
are located from $3F00 to $3FEF. See Figure 2-1.
Twelve of the user vectors, $3FF4–$3FFF, are dedicated to user-
defined reset and interrupt vectors. The remaining four bytes from
$3FF0–$3FF3 are not used.
