This section contains abbreviations and specialist words used in this data
sheet and throughout the industry. Further information on many of the terms
may be gleaned from Motorola’s M68HC11 Reference Manual,
M68HC11RM/AD , or from a variety of standard electronics text books.
The digits following the ‘$’ are in hexadecimal format.
The digits following the ‘%’ are in binary format.
Analog-to-digital (converter).
In this mode the device automatically loads its internal memory from an
external source on reset and then allows this program to be executed.
Eight bits.
Condition codes register; an integral part of the CPU.
A ceramic package type, principally used for EPROM and high temperature
devices.
‘0’ — the logic zero state; the opposite of ‘set’.
Complementary metal oxide semiconductor. A semiconductor technology
chosen for its low power consumption and good noise immunity.
Computer operating properly. aka ‘watchdog’. This circuit is used to detect
device runaway and provide a means for restoring correct operation.
Central processing unit.
Digital-to-analog (converter).
Electrically erasable programmable read only memory. aka ‘EEROM’.
Erasable programmable read only memory. This type of memory requires
exposure to ultra-violet wavelengths in order to erase previous data. aka
‘PROM’.
Electrostatic discharge.
In this mode the internal address and data bus lines are connected to
external pins. This enables the device to be used in much more complex
systems, where there is a need for external memory for example.
