Description
Software should not rely on the value of a reserved bit. To
provide compatibility with future products, the value of a
reserved bit should be preserved across a
read-modify-write operation.
Selects the delay values that are added to the FPLL
feedback clock before being output to the FPLL.
00: No buffer delay
01: One buffer delay
10: Two buffers delay
11: Three buffers delay
Selects the delay values that are added to the FPLL
reference clock before being output to the FPLL.

When 1, holds the DDR_FIC (AXI/AHB) interface
controller in reset.
When 1, holds the FDDR subsystem in reset.

Indicates override of the calibration value from the
pc code / programmed code values in the DDRIO
calibration block.
