3.3 J7 – External Peripheral Interface Header

Header J7 contains all the signals for the MSP432E411Y’s External Peripheral Interface (EPI). The EPI can be connected to an onboard IS42S16320F-7TL – 512 megabit SDRAM, U2, buy shorting all the header pins on J7 horizontally, as shown in Figure 5. Alternatively, the EPI pins can be used to connect to an external device by removing the headers on J7, and connecting to the outside pins of J7, as shown in Figure 6.
