Q-cycles
This is the same as a device oscillator cycle. There are 4 Q-cycles for each instruction cycle.
RC
Resistor-Capacitor. The default configuration for the device oscillator. This allows a “Real-Cheap”
implementation for the device clock source. This clock source does not supply an accurate
time-base. Operation to 4 MHz is supported. (See EXTRC).
Read-Modify-Write
This is where a register is read, then modified, and then written back to the original register. This
may be done in one instruction cycle or multiple instruction cycles.
Register File
This is the Data Memory. Contains the SFRs and GPRs.
ROM
Read Only Memory. Memory that is fixed and cannot be modified.
