MICRF505/506 Basic: Handling the control interface

Keywords:radio transceiver? microcontroller? control interface?

MICRF505/MICRF506 operation is controlled through a "control word" or "programming word".

The control word is read/written through the "control interface", which in the RF chip is a "Slave" (note that the RF chip is a "Master" in the separate "data interface"). Typically, a microcontroller is used to control the RF transceiver. Typical strategies are:

Not using any micro controller built-in hardware modules
This should be selected if the micro does not have an available hardware module. Writing and reading are done bit-by-bit, also referred to as "bit-banging".

Using a built-in hardware module
This can be used if the microcontroller has an available hardware module. Typically, a synchronous serial module (like SPI).

This application note emphasizes some of the basic microcontroller procedures used when working with Micrel's MICRF505/MICRF506 radio transceiver: How to handle the "control interface" and how to build the "control word". The actual values used in the control word are not described here.
