* Note: Not supported on the M5-P19 found in a few very early prototype kits (pre. May 2018). The MULTOS version can be checked by using the command hterm -serial COMx -multos where x is the number of the serial port of your Development board. The rom_ic_details value will be 0x84 0x53 for M5-P22. The build number of the operating system can be obtained using the command hterm -serial COMx -apdu 80100A0006 .
