QSPI
A 64 Mbit Quad SPI (MX25R6435F) flash is available on the BMD-345-EVAL. This memory can be used
for execute in place (XIP) directly from the flash as well as general data storage.

GPIO jumpers
Many solder bridge jumpers on the board are available to allow GPIO configuration. Most solder
jumpers are used to remove on-board components from the module’s GPIO nets to eliminate
interference with external circuitry added on the I/O headers. All GPIOs are directly connected to the
I/O Headers by default, except P0.00 & P0.01 (32 kHz crystal), P0.09 & P0.10 (NFC antenna), and
P0.17 & P0.20 - P0.23 (QSPI). These are disconnected from the I/O headers as they would interfere
with the default functions. The GPIO jumpers are shown on the bottom of the BMD-345 evaluation kit
PCB.
