25 / 88 page  Doc ID 022952 Rev 2 25/88 VD5377 I/O description 5.2 LED_OUT (tracking LED) and GPIO0 LED_OUT is controlled by a 3-bit current DAC (0x3 ANALOG_CTRL2 bits [6:4]) capable of driving up to 14 mA (current sink). Where higher power output is required, an external LED driver can be used controlled by GPIO0 (0x3 ANALOG_CTRL2 bit7 and 0xd GPIO_GPIO0 bit 4). Figure 11 shows the two LED drive options. LED pulse timing is controlled automatically (see Figure 12). GPIO0 can also be used as a general purpose I/O and is configured using register 0xd GPIO_GPIO0 bit 4. A typical configuration of a GPIO is shown in Figure 13 on page 27. Figure 11. LED drive options Figure 12.
