Preliminary
Entity 20: Reset and Power-on Logic (CRSET)
This entity performs BIST and flush operations. Chip software resets can be controlled by this entity, as well
as the chip clock control.
Reset and Power-on Logic Registers
20.1: Reset Status Register
This register is used to reflect the last type of reset was. A hardware reset will clear software reset status bits,
but a software reset will not have an affect on the hardware status bits.

XXXX 0500
’DB00001’ or ’DB00010’, where B is the state of the BIST results, and D is the PLL
phase detection.
’DB001QQ’ or ’DB010QQ’, where Q is the state of this bit before the software reset
and B is the state of the BIST results.
None
A value of ’1’ means that the real time PCI frequency calculator has detected a major
change in frequency and has calculated new range bits for the PLL.
A value of ’1’ means that the out-of-phase detector circuit has triggered. This is just an
indicator and is normal operation.
A value of ’1’ means that a failure occurred within the BIST checking logic.
The PCORE entity has been reset via a software reset request (bit 3 of Software Reset
Register).
A POR Hardware Reset that flushed the chip has occurred.
Reserved
A Software Reset has occurred; the chip was flushed.
A Software Reset has occurred; and BIST/flush was run.
