REGISTER 2-46: IFGAP (INTER FRAME CONFIGURATION REGISTER)
R-000
R/W-10111
r
IFGAP<4:0>
bit 7
ADDRESS 0x39
bit 0
Legend: R = Readable bit W = Writable bit
-n = Value at POR
‘1’ = Bit is set
r = Reserved
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-5
bit 4-0
Reserved: Maintain as ‘0’
IFGAP<4:0>: TX Interframe-Gap Field bits
This field allows configuring a TX interframe-gap ranging from 0 to 30 μs. This duration is enforced as
a minimum separation between the last sample of a transmitted frame and the start of the preamble for
a potential subsequent frame transmission. Unit is 2 μs/LSB.
REGISTER 2-47: TXPOW (TRANSMIT POWER CONFIGURATION REGISTER)
R/W-000
R/W-11111
CHIPBOOST<2:0>
bit 7
TXPOW<4:0>
ADDRESS 0x3A
bit 0
Legend: R = Readable bit W = Writable bit
-n = Value at POR
‘1’ = Bit is set
r = Reserved
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-5
bit 4-0
CHIPBOOST<2:0>: TX Chip Boosting Field bits
This field modifies the spectrum of the OQPSK transmission.
TXPOW<4:0>: TX Power Register Field bits
This field allows configuring a TX power ranging from -19 to 1 dBm. Encoding:
11111 = +1 dBm

•
00001 = -19 dBm
00000 = PA OFF
