Data Bus
The bus which is used to transfer data to and from the data memory.
Data EEPROM
Data Electrically Erasable Programmable Read Only Memory. This memory has the capability to
be programmed and re-programmed by the CPU to ensure that in the case of a power loss critical
values/variables are retained in the non-volatile memory.
Data Memory
The memory that is on the Data Bus. This memory is volatile (SRAM) and contains both the Spe-
cial Function Registers and General Purpose Registers.
Direct Addressing
When the Data Memory Address is contained in the Instruction. The execution of this type of
instruction will always access the data at the embedded address.
Digital to Analog
EEPROM
Electrically Erasable Programmable Read Only Memory. This memory has the capability to be
programmed and erased in-circuit.
EPROM
Electrically Programmable Read Only Memory. This memory has the capability to be pro-
grammed in-circuit. Erasing requires that the program memory be exposed to UV light.
EXTRC
External Resistor-Capacitor (RC). Some devices have a device oscillator option that allows the
clock to come from an external RC. This is the same as RC mode on some devices.
Flash Memory
This memory has the capability to be programmed and erased in-circuit. Program Memory tech-
nology that is almost functionally equivalent to Program EEPROM Memory.
Fosc
Frequency of the device oscillator.
