Lower 16 bits of capture memory data word.
Read only register which records memory location of input trigger point. 2
Selects use of test inputs
Software generated logic reset, which when high, resets the pre-distorter circuitry. Low is default.
Higher 16 bits of capture memory data word. Writing to this address triggers the write to the memory and
increments the address counter when address auto increment, control word 0x04, bit 13 is set. Must write
control word 0x0c first, to load the data values into memory.
Not used.
Read only register with status defined as:
00 - Idle, Memory access OK.
01 - Armed. Capture memory waiting for trigger.
10 - Loading. Capture memory in load mode.
11 - Send. Memory sends data to downstream modules.
Not used.
00 - Idle, Memory access OK.
01 - Armed. Capture memory waiting for trigger.
10 - Loading. Capture memory in load mode.
Not used.
Read only register which records memory location of feedback trigger point. 2
Not used.
0 - Off. IIN<17:0>, QIN<17:0> in use for input stream.
1 - On. Use capture memory output for pre-Distorter input. Note: Test inputs are 16-bits wide and are MSB
justified onto the pre-distorter 20-bit inputs by setting the four LSB’s to zero.
Disables processing and allows input data to flow to output without any pre-distorter modification.
0 - Pre-distorter is active and processing.
1 - Pre-distorter is bypassed.
