612_OMU_S2_URT_V1_13 Firmware Description Document FDD_6612_010 3 Serial Communication The serial communication with the 78M6612 takes place over a UART (UART0) interface. The default settings for the UART of the 78M6612 are given below: Baud Rate: Data Bits: Parity: Stop Bits: Flow Control: 38400bps 8 None 1 Xon/Xoff The host’s serial interface port is required to implement these settings on its UART.

FDD_6612_ 010 4.2 6612_OMU_S2_URT_V1_13 Firmware Description Document Reset Commands A soft reset of the 78M6612 can be performed by using the Z command. The soft reset restarts code execution at addr 0000 but does not alter flash contents. To issue a soft reset to the 78M6612, the host sends the following: >Z The W command acts like a hardware reset. The energy accumulators in XRAM will retain their values. Z Reset Description: Allows the user to cause soft resets. Usage: Z Soft reset.

6612_OMU_S2_URT_V1_13 Firmware Description Document FDD_6612_010 Auxiliary Description: Various Commands: , Typing a comma (“,”) repeats the command issued from the previous command line. This is very helpful when examining the value at a certain address over time, such as the CE DRAM address for the temperature. / The slash (“/”) is useful to separate comments from commands when sending macro text files via the serial interface. All characters in a line after the slash are ignored. 4.

FDD_6612_ 010 6612_OMU_S2_URT_V1_13 Firmware Description Document The device will calibrate the temperature, calibrate the voltage, and finally calibrate the power and save all values to flash. The commands are summarized in the table below: CALx Complete Calibration Commands Description: Allows the user to Calibrate the IC. Usage: CAL Calibrates temperature, then voltage, and finally current for Outlet 1. CAL2 Calibrates temperature, then voltage, and finally current for Outlet 2.

FDD_6612_ 010 4.6 6612_OMU_S2_URT_V1_13 Firmware Description Document CE Data Access Commands The CE is the main signal processing unit in the 78M6612. The user writes to the CE data space are mainly for calibration purposes. The 78M6612 OMU demo units and 78M6612 AC-PMON demo units come pre-calibrated. No user writes to the CE data space are necessary. For the advanced user, details of CE data access commands are given.

6612_OMU_S2_URT_V1_13 Firmware Description Document FDD_6612_010 4.6.3 U Command The U command is used for updating default values of the CE Data in flash. The description is given in the CE control Command section. Additional examples are provided in the table that follows: ] CE Data Access Description: Allows user to read from and write to CE data space. Usage: ] {Starting CE Data Address}{option}…{option} Command Combinations: ]saddr? Read 32-bit word in decimal.

FDD_6612_ 010 4.7 6612_OMU_S2_URT_V1_13 Firmware Description Document CE Control Commands The most pertinent command is the enable command, CEn. It is mainly used to turn the CE on or off such that the CE data contents can be updated in flash using the U command. The CE is normally on but in order to update the CE data entry, the CE must first be turned off using the CE0. 4.7.1 CE Data Write If the cal coefficient for the IA current input is changed: >]08=FFFFC9B0 4.7.

6612_OMU_S2_URT_V1_13 Firmware Description Document 4.8 FDD_6612_010 I/O RAM (Configuration RAM) Command The RI command is used for altering the I/O RAM contents. This is usually not necessary as the FW defaults these settings appropriately. One case where the RI command could be used would be to speed up the accumulation interval for energy measurements.

FDD_6612_ 010 6612_OMU_S2_URT_V1_13 Firmware Description Document 5 MPU Measurement Outputs This section describes the measurement outputs that can be obtained. Energy outputs are accumulated numbers. The default accumulation interval is 1 second (999.75 ms). The host accessing the measurement information from the 78M6612 more frequently will not result in any update in the information. The accumulation interval is set by the following: 0.
