To allocate a set of test points to a TMU:
Registry path:
Keyword:
Default setting at delivery:
Set the Byte 0 of keyword in the range 1 to 4 to select test points Set # 1 to Set # 4
Additional settings:
Byte 1 bit 0:
0 for Data Out Updated on Rising edge of Clk Out, Data In sampled on Falling edge of Clk In
1 for Data Out Updated on Falling edge of Clk Out, Data In sampled on Rising edge of Clk In
Byte 1 bit 2:
0 fo I/Q ambiguity not managed on test points
1 for enabling the automatic management of the I/Q ambiguity in QPSK modes
Byte 1 bit 3:
0 for LVTTL
1 for RS422

Bits 4 to 7:
Output gain shift value
Bits 8 to 15:
Output gain mantissa value
From the output gain shift and mantissa values, the signal gain is computed as:
