Table 12 Address of receiver #2 and receiver #1.
Bit 103 – 64:
ADDR2: Receiver address channel 2, up to 40 bit.
Bit 63 – 24: ADDR1
ADDR1: Receiver address channel 1, up to 40 bit.
NOTE!
Bits in ADDRx exceeding the address width set in ADDR_W are redundant
and can be set to logic 0.

Table 13 Number of bits reserved for RX address + CRC setting.
Bit 23 – 18:
ADDR_W: Number of bits reserved for RX address in ShockBurst™
packages.
NOTE:
Maximum number of address bits is 40 (5 bytes). Values over 40 in
ADDR_W are not valid.
Bit 17:
CRC_L:
CRC length to be calculated by nRF2401A in ShockBurst™.
Logic 0: 8 bit CRC
Logic 1: 16 bit CRC
Bit: 16:
CRC_EN:
Enables on-chip CRC generation (TX) and verification (RX).
Logic 0: On-chip CRC generation/checking disabled
Logic 1: On-chip CRC generation/checking enabled
NOTE:
An 8 bit CRC will increase the number of payload bits possible in each
ShockBurst™ data packet, but will also reduce the system integrity.
