nRF24L01 Product Specification
The W_REGISTER and R_REGISTER commands can operate on single or multi-byte registers. When
accessing multi-byte registers you read or write to the MSBit of LSByte first. You can terminate the writing
before all bytes in a multi-byte register are written, leaving the unwritten MSByte(s) unchanged. For exam-
ple, the LSByte of RX_ADDR_P0 can be modified by writing only one byte to the RX_ADDR_P0 register. The
content of the status register is always read to MISO after a high to low transition on CSN.
