LED Data Register (PX_LED)
The LED data register can directly control indicator LEDs; for example, for software message purposes.
Direct LED control is only possible if PX_CSR[LED] is set to ‘1’.

FPGA TAG (PX_TAG)
The FPGA TAG register contains the following information: embedded FPGA build date, minor revisions,
image name, and so on.
NOTE
Type “ngPIXIS INFO” under eDINK to display FPGA TAG register data.
