APPENDIX A
MC68HC705PD6
This appendix describes the differences between the MC68HC705PD6 and
MC68HC05PD6.
A.1
INTRODUCTION
The MC68HC705PD6 is an EPROM version of the MC68HC05PD6, and is
available for user system evaluation and debugging. The MC68HC705PD6 is
functionally identical to the MC68HC05PD6 with the exception of the 16400 bytes
user ROM is replaced by 16400 bytes user EPROM. Also, the mask options
available on the MC68HC05PD6 are implemented using the Mask Option
Register (MOSR) in the MC68HC705PD6.
The MC68HC705PD6 is available in 80-pin Quad-Flat-Package (QFP).
A.2
MEMORY
The MC68HC705PD6 memory map is shown in Figure A-1.
A.3
MASK OPTION REGISTER (MOSR), $000F
The Mask Option Register (MOSR) is a byte of EPROM used to select the
features controlled by mask options on the MC68HC05PD6.
RSTR – RESET pin pull-up resistor
