Setup
2.3.3 EVM With Microcontroller
The following settings are provided to use the EVM with a microcontroller:
• Put the S_ON_OFF selector in the OFF position.
• Set the mode of operation through the MODE header (see Table 3 ).
• Connect the microcontroller to the IO header in order to manage the I/O signal of the design under test
(DUT).
• Supply the microcontroller, connecting its supply pin to the AUX_VDD test point and the ground to the
GND pin of the IO header.
• Insert a CR2032 coin cell battery in the battery holder (BT), alternatively, connect a voltage source
between the AUX_VDD and GND test points.
• Configure the jumper J1 (RSTn connected to IO, WAKE connected to IO) and J2 (DONE connected to
IO), as explained in
Table 3 .
NOTE: Do not connect the coin cell battery and the voltage source to supply the evaluation board at
same time.
Do not use the switch S2 (DONE), in this configuration the DONE switch is connected to a
digital output pin of the microcontroller.
• Put the S_ON_OFF selector in the ON position, or turn on the external voltage source if it is used
instead of the coin cell battery.
