RW

logical refclk selection

When written initiates reference clock

change to the logical reference clock

indexed by bits [2:0].
This index refers to the Number of

input clocks on the Reconfiguration

tab. You can specify up to 5 input

clocks. When performing a reference

clock switch for an ATX PLL you

must stream in an ATX MIF.
This offset is used to switch the

reference clock for CMU PLLs. To

perform a reference clock switch for

ATX PLLs use MIF mode 0 and

stream the ATX PLL MIF.

0x1

[2:0]

RW

logical PLL selection

When written initiates a clock

generation block (CGB) switch to

logical PLL indexed by bits [2:0].
This index refers to the Number of

TX PLLs selected on the Reconfigu‐

ration tab. You can specify up to 4

input clocks. If you set the Main TX

PLL logical index to 0, the Quartus II

software initializes your design using

the first PLL defined.

0x2

[24:0] RO

refclk physical mapping

Specifies the logical to physical refclk

for current logical channel.

0x3

[14:0] RO

PLL physical mapping

Specifies the logical to physical clock

generation block word for current

logical channel.
