Note: GPIO_3/LINK_IND has a 10 mA IOH or IOL driver current that can be used for an LED. By default, the
drive strength settings specified in Table 12 are for 3.3V. To achieve the required drive strength for a VDDO of
2.5V or 1.8V, contact a Broadcom technical support representative (see “Technical Support” on page 8 for
contact information).
