TX_SD

R/W

10:5

4:0

Ends low flag for Manchester

encoding

Invert amplitude I

Invert amplitude Q

Enable I sign switching

Enable Q sign switching

LUT start address

Number of samples

h0000

TX microcode table for

user defined instructions,

16 registers.

The “ends low” flag is used

for Manchester encoding

to determine whether the

programmed symbol ends

low.

The invert amplitude flag

inverts the LUT value

stored, i.e., output =

1-LUT.

The sign switching bits

determine if the sign

switches at the start of the

instruction. The LUT start

address is zero indexed.

Hold value

h0000

TX microcode table for

user defined instructions,

16 registers.

Determines how long the

last sample of the LUT

command shall be held.

Specified in TX clock

cycles.
