APPENDIX A
MC68HC705SB7
This
appendix
describes
the
MC68HC705SB7,
the
emulation
part
for
MC68HC05SB7. The
entire
MC68HC05SB7
data

A.1
INTRODUCTION
The MC68HC705SB7 is an EPROM version of the MC68HC05SB7, and is avail-
able for user system evaluation and debugging. The MC68HC705SB7 is function-
ally identical to the MC68HC05SB7 with the exception of the 6106 bytes user
ROM is replaced by 6106 bytes user EPROM. The mask option for the external
pin oscillator on the MC68HC05SB7 is controlled by the Mask Option Register at
$002F on the MC68HC705SB7. This device is available in 28-pin SOIC package.
