Appendix: Rate Select Control
RX and TX rates can be independently controlled by either hardware input pins or via register writes. Module electri-
cal input pins 7 and 9 are used to select RX and TX rate respectively. Status of each logic level is reflected 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 flexible control.
