Prints the version number of ALFAT SoC firmware. Note that this version is not the
same or related to the version number of the boot loader.
Enabling echo makes ALFAT echos back the data it receives over UART.
Echo is disabled by default.
ALFAT supports two low power modes

Commands must have the exact formatting. Extra spaces are not allowed.
All numbers are Hexadecimal represented in ASCII. For example, to send the
decimal number 16 to ALFAT SoC which is 10 in Hexadecimal, you send 0x31
which is ASCII for 1 and 0x30 which is ASCII for 0. Also, for Hexadecimal numbers
A to F, they must be entered in upper case letters. If using a terminal to enter
commands manually, then only type in the number.
Some commands have multiple error codes. Usually, the first error code denotes
the command is accepted and then it is processed. Another error code is sent when
the command has finished processing successfully. If the first error code was a no
success then the command is terminated. Note that the second error code will
never be sent.
All commands that accept file name, such as O and D commands, require a full file
path. File name is not enough. For example, “U1:\folder\data.log” is good but
“data.log” shouldn't be used.
ALFAT command's terminator can be LF('\n') or CR ('\r').
Standby Mode: This mode will completely turn off the processor.
