Control and I/O Signals

All of the control and I/O signals from DA9214 appear on the headers pins shown above. These are
the most useful monitor points for debug purposes.
If required, a suitable connector can bring these signals to the system board for integrated
development. If used in this way, the other links which also control these pins should be removed to
avoid logic or voltage clashes.
The arrangement of the jumper links to the GPIO pins is shown in
inserted on J27 for USB control and monitor. The jumpers can also be placed on the headers J22,
J24, J25 as follows:
●
Between J22 and J24, connecting GPIOs to VDD_IO via 100 kΩ pull up resistor
●
Between J24 and J25, connecting GPIOs to ground via 100 kΩ pull down resistor
●
Left open for external connections
