LED MODE SELECT
The device LED outputs are controlled using the bits in register 29 of the main register space. The following table shows
the information needed to access the functionality of each of the outputs. For more information about LED modes, see
Table 5-14. For information about enabling the extended LED mode bits in Register 19E1 bits 13 to 12, see Table 5-16
.
