Function
0: use SDIO pin as input data only
1: use SDIO as both input and output data
0: first bit of serial data is MSB of data byte
1: first bit of serial data is LSB of data byte
Bit must be written with a 1, then 0 to soft
reset SPI register map
0: all circuitry is active
1: disable all digital and analog circuitry,
only SPI port is active
Controls auto power-down mode, see the
Power-Down and Sleep Modes section
0: PLL is not locked
1: PLL is locked
00: 1× interpolation
01: 2× interpolation
10: 4× interpolation
11: 8× interpolation
See Table 21 for filter modes
0: zero stuffing off
1: zero stuffing on
0: signed binary
1: unsigned binary
0: both input data ports receive data
1: Data Port 1 only receives data
0: enable Q path for signal processing
1: disable Q path data (internal Q channel
clocks disabled, I and Q modulators
disabled)
See the Using Data Delay to Meet Timing
Requirements section.
0: inverse sinc filter disabled
1: inverse sinc filter enabled
0: output DATACLK same phase as internal
capture clock
1: output DATACLK opposite phase as
internal capture clock
Inverts the function of TxEnable Pin 39, see
the Interleaved Data Mode section
0: first byte of data is always I data at
beginning of transmit
1: first byte of data is always Q data at
beginning of transmit
00: manual
Data clock output divider (see Table 22 for
divider ratio)
Sets delay of REFCLK in to DATACLK out
Sets frequency of SYNC_O pulses
Sync output delay, Bit 4
Sync output delay, Bits<3:0>
Input sync pulse frequency divider, see the
AN-822
Sync input delay, Bit 4
