2.15.3.3 MMC2 - M2 Key E Interface

The AM62x-Low Power SK EVM has an M.2 Key E interface for connecting WiFi BT modules connected to MMC2, UART2 instances and McASP1 interface through buffers. The M.2 module is connected to 4-bit IO of the MMC2 interface. The Module requires one power supply, 3.3V. Power to M.2 module is supplied from on-board power supply rails.

The MMC2 interface of the SoC is powered by the VDDSHV6 power domain, which is connected to 1.8V IO supply.
