RxSetup1
Title:
First Receive Set-up control register
Address:
$0x08
Function:
RW
Description:
Receive path set-up and initialisation control bits.
Bit
Name
Active State
Function
7
Rx32BitMode
High
RW
When set active, the Rx port operates on 32-bit frames -
I data in the MSB word, Q data in the LSB word.
6
RxSampleSel
High
RW
This bit is used to select which pair of I,Q samples is
supplied from the possible two when the DataRateHi bit in
ConfigCtrl1 register is in the low mode (inactive). It has no
effect when DataRateHi is active.
5
RxClkStop
High
RW
When set active causes the RxEn bit to also be used to
gate the Rx Data path master clock. When inactive (default
state) the Rx Data path master clock is always supplied.
4
RxEn
High
RW
When set active, enables the Rx Data path, which then
starts to process the differential data on the IRXP,IRXN
and QRXP,QRXN pins, outputting results via the Rx serial
port. This bit also acts as a receive section power enable
bit.
3
RxBistActive
High
RW
When set active, enables Rx Built-In Self Test (BIST)
operation.
2
AnaAdcReset
Pulse W
When this bit is set High, a 4-clock-cycle ADC auto reset
event is generated. It is not necessary to clear this bit
before another ADC auto reset event is initiated.
R
The read state of this bit indicates the logic level last written
to this bit. It does not have a functional significance and is
only available for test purposes.
1
AnaEnAutoReset
Low
RW
When active this bit enables the ADC auto reset function.
On taking N_RESET Low, this bit is set active, which is the
default operating condition.
0
RxFirCoeffReset
Low
RW
When set active forces all the Rx Data path filters to load
their default coefficient values. This bit will be set active on
taking N_RESET Low, and therefore needs to be
deactivated before default filter coefficients can be
overwritten. Normal filter operation is unaffected by leaving
this bit set.
