ADDR2: Receiver address channel 2, up to 40 bit.
ADDR1: Receiver address channel 1, up to 40 bit.
Bits in ADDRx exceeding the address width set in ADDR_W are redundant
and can be set to logic 0.
ADDR_W: Number of bits reserved for RX address in ShockBurst™
packages.
NOTE:
CRC_L:
CRC_EN:
NOTE:
Table 13 Number of bits reserved for RX address + CRC setting.

Maximum number of address bits is 40 (5 bytes). Values over 40 in
ADDR_W are not valid.
An 8 bit CRC will increase the number of payload bits possible in each
ShockBurst™ data packet, but will also reduce the system integrity.
