3.1 Carrier Frequencies
ST7538 is a multi frequency device: eight programmable Carrier Frequencies are available (see table 6).
Only one Carrier at a time can be used; anyway, it's possible to switch the communication channel during
the normal working Mode. Selecting the desired frequency in the Control Register the Transmission and
Reception filters are accordingly tuned.
