RF BAND RESISTORS
Four resistors Ra, Rb, Rc, and Rd are responsible to start the microcontroller in a RF band.
Table 2 shows the reference designators and how the voltages at the test points reflect the operating RF band.
.
Table 3 shows the variant resistor installation options for each band. When a resistor is installed the microprocessor will read a logic low,
otherwise it will read a logic high..
