FUNCTION
Reserved.
Output LSBytes, bits (7:0), of AOUT and BOUT can provide:
0- Buffer RAM Mode Output or.
1- Parallel Direct Mode Output.
Buffered Mode Output interfaces to either:
0- 8-bit P (address = P ASEL(5:#); CLK = P RAM read).
1- 16-bit P (address = SEL(2:0); CLK = OEBL).
The data word sent by the Direct Parallel Output Mode to AOUT is:
00- I Data.
01- Magnitude.
1X- Frequency.
The data word sent by the Direct Parallel Output Mode to BOUT is:
00- Q Data.
01- Phase.
1X- Magnitude.
0- Normal Sync Mode (active high).
1- Sync Inverted (active low).
0- Output Clock Inverted rising edge aligns with data transitions.
1- Output Clock Normal falling edge aligns with data transitions.
0- Sync is asserted one bit time after the last bit of the serial word (Late Mode).
1- Sync is asserted one bit time prior to the first bit of the serial word (Early Mode).
000- Serial Output at PROCCLK/16.
001- Serial Output at PROCCLK/8.
010- Serial Output at PROCCLK/4.
011- Serial Output at PROCCLK/2.
1XX- Serial Output at PROCCLK rate.
00- No Tag Bit. LSB of word is passed.
01- 0 Tag Bit. LSB of word is set to zero.
1X- 1 Tag Bit. LSB of word is set to one.
