29.6.3. Phase Reconfig Control Register

Embedded software can control the dynamic phase reconfiguration via the phase reconfig control register.
Table 288.  Phase Reconfig Control Register Bits
Bit Number Bit Name Value after reset Description
0:8 counter_number A binary 9-bit representation of the counter that needs to be reconfigured. Refer to the Counter_Number Bits and Selection table for the counter selection.
9:29 Reserved. Read values are undefined. When writing, set reserved bits to zero.
30:31 phase (1) 01: Step up phase of counter_number

10: Step down phase of counter_number

00 and 11: No operation

Note :
  1. Phase step up or down when set to 1 (only applicable to the Avalon® ALTPLL core).

The table below lists the counter number and selection. For example, 100 000 000 selects counter C0 and 100 000 001 selects counter C1.
