I would like to use GPIO on TWR-LS1021A.
I read TWR-LS1021A Reference Manual 2.21 and 3.1, and understood some pin of card edge connector is mapped to GPIO.
But I cannot understand what "GPIOn" (e.g. GPIO14) in the Table 3-1 means.
In TWR-LS1021A, there are 4 GPIO module and each of them has its own port.
Therefore, it seems it should be written as "GPIO_m[n]".
In the table of the reference manual, which port is mapped to "GPIOn"?
