Control Registers
The following tables describe the function of each control register along with the associated bits in each control register.
CONFIGURATION REGISTER 0 ADDRESS (0h) R PART/VERSION CODE
Bit 7:4
Part Code
3 = HFA3863 series
Bit 3:0
Version Code
0 = 3863 Version
CONFIGURATION REGISTER 1 ADDRESS (02h) R/W I/O POLARITY
This register is used to define the phase of clocks and other interface signals. 00h is normal setting.
Bit 7
This control bit selects the phase of the receive carrier rotation sense.
Logic 1 = Inverted rotation (CW), Invert Q in.
Logic 0 = normal rotation (CCW).
Bit 6
This control bit selects the phase of the transmit carrier rotation sense.
Logic 1 = Inverted rotation (CW), Invert Q out.
Logic 0 = normal rotation (CCW).
Bit 5
This control bit selects the phase of the transmit output clock (TXCLK) pin.
Logic 1 = Inverted TXCLK.
Logic 0 = NON-Inverted TXCLK.
Bit 4
This control bit selects the active level of the Transmit Ready (TX_RDY) output which is an output pin at the test port, pin.
Logic 1 = TX_RDY Active 0.
Logic 0 = TX_RDY Active 1.
Bit 3
This control bit selects the active level of the transmit enable (TX_PE) input pin.
Logic 1 = TX_PE Active 0.
Logic 0 = TX_PE Active 1.
Bit 2
This control bit selects the active level of the Clear Channel Assessment (CCA) output pin.
Logic 1 = CCA Active 1.
Logic 0 = CCA Active 0.
Bit 1
This control bit selects the active level of the MD_RDY output pin.
Logic 1 = MD_RDY is Active 0.
Logic 0 = MD_RDY is Active 1.
Bit 0
This controls the phase of the RX_CLK output.
Logic 1 = Invert Clk.
Logic 0 = Non-Inverted Clk.
CONFIGURATION REGISTER 2 ADDRESS (04h) R/W RX CONFIGURE
Write to control, Read to verify control, setup while TX_PE and RX_PE are low
Bits 7:1
Reserved.
Bit 0
Initialization.
0 = Normal Operation.
1 = Soft Initialization of learned behavior registers such as DCoffset, NoiseFloor, FAR, RecPacketsNOcs1, and
RecPacketsUSEdef. Holds AGC logic reset. At part initialization, must be set, then after CR47 is loaded, cleared.
CONFIGURATION REGISTER 3 ADDRESS (06h) R/W TX PREAMBLE LENGTH FOR SHORT PREAMBLE
Bits 0 - 7
This register contains the count for the Preamble length counter for short preambles selected by CR5 bit 3. Setup while TX_PE
is low. For IEEE 802.11 use38h. For other than IEEE 802.11 applications, in general increasing the preamble length will improve
low signal to noise acquisition performance at the cost of greater link overhead. The minimum suggested value is 56d = 38h. A 2
symbol TX power amplifier ramp up is added to programmed value.
CONFIGURATION REGISTER 4 ADDRESS (08h) R/W TX PREAMBLE LENGTH FOR LONG PREAMBLE
Bits 0 - 7
This register contains the count for the Preamble length counter for long preambles selected with CR5 bit 3 or CR11 bit 4.
Setup whileTX_PE islow.
For IEEE802.11 use80h
.ForotherthanIEEE802.11applications,ingeneralincreasingthepreamble
length will improve low signal to noise acquisition performance at the cost of greater link overhead. The minimum suggested value
is 56d = 38h. A 2 symbol TX power amplifier ramp up is added to programmed value. If you program 128 you get 130.
