Allows user to print out MIO configurations
Given the MIO configuration value and which MIO pin, this will decode into a description of the pin.
Example usage
void PrintMIO(uint32_t val, int mio)
{
MioDescrition desc = DescribeZynqMio(val, mio);
printf("MIO%2d ",mio);
printf("%s ", desc.disable_hstl_input?"disable":"enable ");
printf("%s ", desc.pull_up?"pull up":" ");
switch(desc.type)
{
case LVCMOS18: printf("1.8V "); break;
case LVCMOS25: printf("2.5V "); break;
case LVCMOS33: printf("3.3V "); break;
case HSTL: printf("HSTL "); break;
case RESERVED_000:
case RESERVED_101:
case RESERVED_110:
case RESERVED_111:
default:
printf("%4d ", desc.type);
break;
}
printf("%s ", desc.speed==SPEED_FAST?"FAST ":"SLOW ");
printf("%s ", desc.tri_state_enabled?"TRI":" ");
printf("%08x %s\r\n", val, desc.desc);
}Run the PrintMIO with the following
printf("PIN HSTL PULL UP TYPE SPEED TRI RAW Description\r\n");
volatile uint32_t* pins = (volatile uint32_t*)0xF8000700;
for(int i=0;i<54;i++)
{
PrintMIO(pins[i], i);
}
