Appendix I. Rate Select Control
RX and TX rates can be independently controlled by either hardware input pins or via register writes. Module electrical
input pins 7 and 9 are used to select RX and TX rate respectively. Status of each logic level is refl ected to register byte
110 bit 4 and 5 on address A2h as shown in the diagram below. RX and TX rates can also be controlled by register writes
to byte 110 bit 3 and 118 bit 3. Power on default of these bits are logic low. Hardware and software control inputs are
OR’d to allow fl exible control.
