Read/Write
Capability
Write only Set to 0 to initiate an FPGA reconfiguration.
Read / Write Determines which of the pages of flash memory to use for
FPGA reconfiguration. The flash memory ships with pages 0
and 1 preconfigured.
Read / Write When set to 0, the value in PSR determines the page of
flash memory to use for FPGA reconfiguration. When set to
1, the value in PSS determines the page of flash memory to
use for FPGA reconfiguration.
Read only Holds the current value of the iluminated PGM LEDs (D3-
D4) based on the following encoding:
0 = PGM 0 LED (D4) on and PGM 1 LED (D3) on, and
■
corresponds to the flash memory page for the factory
hardware design
1 = PGM 0 LED (D4) on and PGM 1 LED (D3) off, and
■
corresponds to the flash memory page for the user
hardware 1 design
2 = PGM 0 LED (D4) off and PGM 1 LED (D3) on, and
■
corresponds to the flash memory page for the user
hardware 2 design
