Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

io39_delay Fields

Bit Name Description Access Reset
14:13 output_val_en 
These bits are used to enable the delay chains on the output path.   
00 - Bypasses the delay chain ; 
01 - Selects delay from 0 to 15 chain delay as programmed by the output_val field. ; 
10 - NA ; 
11 - Selects delay from 16 to 30 delay chains as programmed by output_val field.
Value Description
0 Bypasses the delay chains
1 Selects the delay chain ranging from 0 to 15 (Intrinsic IO delay + 1Minimum + xChain delay)
