LED Function 1-0 (LED_FUN[1:0])
These bits control the function associated with each LED pin as shown in
Table 13.1
Note:
LED Enable 7-0 (LED_EN[7:0])
This field toggles the functionality of the GPIO[7:0] pins between GPIO and
LED.
0: Enables the associated pin as a GPIO signal
1: Enables the associated pin as a LED output
LED Configuration Register (LED_CFG)
This read/write register configures the GPIO[7:0] pins as LED[7:0] pins and sets their functionality.
Note 14.2 The default value of this field is determined by the configuration strap LED_fun_strap[1:0].
Note 14.3 The default value of this field is determined by the configuration strap LED_en_strap[7:0].
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.

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
