4.12.4 Power Measurement
The MITX-CORE-820 design provides the ability to measure power consumption on DC-IN
supply rails.
4.13 Embedded Controller
The MITX-CORE-820 design implements a Nuvoton NPCE791C embedded controller. The
following sections list the functionality of the embedded controller, or EC.
4.13.1 Voltage Monitor
The MITX-CORE-820 design implements voltage monitoring capability on +V3A, +V5A and
+V1.5S rails. The ADC of EC can be used as voltage monitor.
4.13.2 Serial Port
EC implements one RS-232 compatible serial port on the rear IO. It has RXD, TXD, RTS#, CTS#
and RI# signals on the port.
