Make sure that no shorts are connected to either GND or VCC on any of the pin mode headers. Once the user has verified that no pins have been shorted and the threat of destroying the IO expander or MCU has been eliminated, then provide power using any of the four scenarios described Table 3-7. Current draw must be approximately 0.9 V after power is applied.
Next, the user must configure the IO expander. This is done by pressing the Configure Driver button in the GUI under the light green PIN MODES section.
Successful configuration of the IO expander results in a TCA9535 one-time configuration complete. Re-run if USB2ANY is disconnected.
The user is now able to change the states of the pin mode headers via the IO expander by pulling pins either LOW or HIGH directly without the need of a physical short.
CLKx_EN and Device mode options.
Chooses RF output power for all CLKOUTx.
Chooses the corresponding divider value when in divider mode or multiplier value in multiplier mode.
