Description
These are the Silicon ID revision bits. 0000 = Rev A, 0001 = Rev B, etc. These bits are read-only.
These are the Product ID revision bits. Fixed at value 0111. These bits are read-only.
Description
The Receive Enable bit is used to place the IC in receive mode.
The Transmit Enable bit is used to place the IC in transmit mode.
This bit applies only when the Code Width bit is set to 32 chips/bit PN codes (Reg 0x04, bit 2=1).
This bit controls whether the state machine waits for the internal Syn Lock Signal before waiting for the amount of time
specified in the Syn Lock Count register (Reg 0x38), in units of 2 us. If the internal Syn Lock Signal is used then set
Syn Lock Count to 25 to provide additional assurance that the synthesizer has settled.
It is recommended that the application MCU sets this bit to 1 in order to guarantee a consistent settle time for the
synthesizer.
The Auto Internal PA Disable bit is used to determine the method of controlling the Internal Power Amplifier. The two
options are automatic control by the baseband or by firmware through register writes. For external PA usage, please
see the description of the REG_ANALOG_CTL register (Reg 0x20).
When this bit is set to 1, the enabled state of the Internal PA is directly controlled by bit Internal PA Enable (Reg 0x03,
bit 2). It is recommended that this bit is set to 0, leaving the PA control to the baseband.
The Internal PA Enable bit is used to enable or disable the Internal Power Amplifier.
This bit only applies when the Auto Internal PA Disable bit is selected (Reg 0x03, bit 3=1), otherwise this bit is don’t care.
This bit is reserved and should be written with a one.
This bit is reserved and should be written with a zero.
