The AM263x LaunchPad has a 128 Mbit QSPI Flash memory device (S25FL128SAGNFI000), which is connected to the QSPI0 interface of the AM263x SoC. The QSPI interface supports single data rates with memory speeds up to 104 MHz. The QSPI flash is powered by the 3.3V system supply.
The QSPI0_D0/D1 signals are also used for BOOTMODE control logic. There are 10KΩ resistors used to isolate the BOOTMODE control logic after the value is latched.
