Part Number: UCD3138

Hello, I was recently learning UCD3138 full-bridge hard-switch firmware
I do not understand the function of void init_variables(void)
Void init_variables(void)
{
   Supply_state = STATE_IDLE;
   Current_share_kp = 40;
   Current_share_ki = 2;
   Fault_status = 0;
   Debug_buffer[0]=1;
   Debug_buffer[1]=2;
   Debug_buffer[2]=3;
   Debug_buffer[3]=4;
   Debug_buffer[4]=5;
   Debug_buffer[5]=6;
   Debug_buffer[6]=7;
   Debug_buffer[7]=8;
}
I do not know debug_buffer[0]=1 ... debug_buffer[7]=8; what is the purpose of this 8-bit array debug_buffer[]?

Debug_buffer can capture 8 variables to serve your debugging needs. This buffer is not essential for the running application itself.
It is just initialized by some fimiliar fixed defaults here that demonstrate that it is initialized and not used yet.
You can overwrite tghis with anything that you want to show in the memory debugger tool.

In other words, the Debug_buffer has no effect on the normal operation of the digital power supply, it is only used during debugging.
So, what will be used when debugging functions?
