This read/write register configures the GPIO[7:0] pins as LED[7:0] pins and sets their functionality.

The default value of this field is determined by the configuration strap LED_fun_strap[1:0].
Configuration strap values are latched on power-on reset or nRST de-assertion. Some
configuration straps can be overridden by values from the EEPROM Loader. Refer to

 for more information.

The default value of this field is determined by the configuration strap LED_en_strap[7:0].
Configuration strap values are latched on power-on reset or nRST de-assertion. Some
configuration straps can be overridden by values from the EEPROM Loader. Refer to

LED Function 1-0 (LED_FUN[1:0])
These bits control the function associated with each LED pin as shown in 

In order for these assignments to be valid, the particular pin must 
be enabled as an LED output pin via the LED_EN[7:0] bits of this 
register.
