1. A method for transmitting tire pressuring monitoring system (TPMS) data, comprising,determining a first protocol to be used in the transmission of tire pressure monitoring data from a transmitter;
- based upon the first protocol, selecting a first deviation between a first high frequency that is used to transmit a logic one and a first low frequency to transmit a logic zero;
transmitting the tire pressure monitoring system (TPMS) data according to the first high frequency when there is a logic one and first low frequency when there is a logic zero;
subsequently determining a second protocol to be used in the transmission of tire pressure data from a transmitter;
based upon the second protocol, selecting a second deviation between a second high frequency that is used to transmit a logic one and a second low frequency to transmit a logic zero;
wherein the first deviation is different than the second deviation;
transmitting TPMS data according to the second high frequency when there is a logic one and second low frequency when there is a logic zero.

Abstract
A protocol to be used in the transmission is determined. Based upon the protocol, the transmission frequency range of a clock is selectively altered. TPMS data is transmitted according to the altered transmission frequency range of the clock.
