Address configuration

The on-air radio ADDRESS field is composed of two parts, the base address field and the address prefix field.

The size of the base address field is configurable via the PCNF1.BALEN register. The base address is truncated from the least significant byte if PCNF1.BALEN is less than 4. See Definition of logical addresses.

The on-air addresses are defined in the BASE0/BASE1 registers and PREFIX0/PREFIX1 registers. It is only when writing these registers that the user must relate to the actual on-air addresses. For other radio address registers, such as the TXADDRESS, RXADDRESSES, and RXMATCH registers, logical radio addresses ranging from 0 to 7 are used. The relationship between the on-air radio addresses and the logical addresses is described in the following table.
