Programmable chip design for radio frequency signal generation and method therefor
First Claim
1. A radio frequency identification (RFID) circuit for generating RFID command signals, the circuit comprising:
- at least one command register, the at least one command register storing at least one command bit, the at least one command bit corresponding to a portion of a command to be transmitted to at least one remote communication device;
at least one table, the at least one table storing wave-shaping transition values for shaping the at least one command bit; and
at least one control register, the at least one control register storing at least one configuration value for shaping the at least one command bit.
