r
TX2IDLE<4:0>
bit 7
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’
TX2IDLE<4:0>: Transmit Power-Down to Idle Duration Field bits
Defines the duration of the interval while PLL cannot be tuned (turned off or change channel) following
that the transmitter and external PA (if PAE = 1) are turned down together.
Representation: 1 μs/1 LSB. No offset.

REGISTER)

TX2TXMA<4:0>: Transmit Power-Up to Medium Access Configuration Field bits
Defines the time interval between turning on the internal transmitter of the device and the start time of
medium access (start of the PHY-layer frame).
TX_TO_TXMA = The transient time of the transmitter, in the following scenarios:
PAEN = 0
PAEN = 1, but the PA is turned on first. PA_TO_TXMA = TX_TO_TXMA + PA transient time.
PAEN = 1, but the TX and PA transients are NOT sequenced.
TX_TO_TXMA = The transient time of the transmitter + PA_TO_TXMA:
PAEN = 1, and the transmitter is turned on first (transients are sequenced).
Representation: 1 μs/1 LSB. No offset.
