2.2 Simple Mode
The RXC101 can be configured for Simple Mode which does not require the use of a processor. All
values on for internal registers are the default values assumed during POR. Even though the device is in
this mode, the SPI bus, pins 1, 2 and 3, are still available to change internal configurations yet remain in
simple mode operation.
