Register Map
There are two register banks, which can be toggled by SPI command “ACTIVATE” followed with 0x53 byte, and
bank status can be read from Bank0_REG7 [7].

Description
Configuration Register
R/W Only '0' allowed
Mask interrupt caused by RX_DR
R/W 1: Interrupt not reflected on the IRQ pin
0: Reflect RX_DR as active low interrupt on the IRQ pin
Mask interrupt caused by TX_DS
R/W 1: Interrupt not reflected on the IRQ pin
0: Reflect TX_DS as active low interrupt on the IRQ pin
Mask interrupt caused by MAX_RT
R/W 1: Interrupt not reflected on the IRQ pin
0: Reflect MAX_RT as active low interrupt on the IRQ pin
R/W
Enable CRC. Forced high if one of the bits in the EN_AA is
high
CRC encoding scheme
R/W '0' - 1 byte
'1' - 2 bytes
R/W 1: POWER UP, 0:POWER DOWN
R/W
RX/TX control,
1: PRX, 0: PTX
Enable ‘Auto Acknowledgment’ Function
R/W Only '00' allowed
R/W Enable auto acknowledgement data pipe 5
R/W Enable auto acknowledgement data pipe 4
R/W Enable auto acknowledgement data pipe 3
R/W Enable auto acknowledgement data pipe 2
R/W Enable auto acknowledgement data pipe 1
R/W Enable auto acknowledgement data pipe 0
Enabled RX Addresses

Setup of Address Widths
(common for all data pipes)
R/W Only '000000' allowed
RX/TX Address field width
'00' - Illegal
R/W
'01' - 3 bytes
'10' - 4 bytes
'11' - 5 bytes
LSB bytes are used if address width is below 5 bytes
