Section 15. EPROM
15.1 Contents
15.2 Introduction
This section describes erasable programmable read-only memory
(EPROM) programming.
15.3 EPROM
The user EPROM consists of 5120 bytes of EPROM from $0B00 to
$1EFF and 16 bytes of user vectors from $1FF0 to $1FFF.
The bootloader ROM and vectors are located from $1F01 to $1FEF.
Twelve of the user vectors, $1FF4 thorough $1FFF, are dedicated to
reset and interrupt vectors. The four remaining locations, $1FF0, $1FF1,
$1FF2 and $1FF3, are general-purpose user EPROM locations.
Location $1F00 is the mask option register (MOR).
The contents of the EPROM cannot be prevented from being viewed
externally, since security is not incorporated into the MC68HC705CT4.
