16.3 OPEN-DRAIN LED OUTPUTS
16.4 LED DRIVER CONNECTIONS
w
The three open-drain outputs ISINKC, ISINKD and ISINKE are alternate functions of the GPIO10,
GPIO11 and GPIO12 pins, respectively (see Section 20). They can drive LEDs connected to LINE,
with a series resistor. Note that the GPIO pins have other alternate functions, which will not be
available that pin is configured as ISINKC, ISINKD or ISINKE.
The recommended connection for LEDs on ISINKA is illustrated in Figure 72.

The recommended connections for LEDs on ISINKC, ISINKD and ISINKE are illustrated in Figure 73.
