    The Digi Microcontroller Assist™ hardware The Digi Microcontroller Assist, or MCA, is a small microcontroller that is deeply integrated into the design of the ConnectCore 8X module. It assists the i.MX 8X processor with advanced operations related to power management, security, and system reliability.

  • Page 32: Reset Control

    The MCA, in cooperation with the PMIC, controls the reset line of the i.MX 8X processor. The SYS_ RESET pin is the main reset input of the ConnectCore 8X module. This pin is a pseudo open-drain with an internal pull up. Asserting the SYS_RESET line low sets the MCA into reset state, and it remains in this state until the line is de-asserted.
