@ -10,9 +10,9 @@ GPIO port configuration registers and it is typical to refer to pins using the
naming scheme "PxN" where x is a character identifying the GPIO port with
which the pin is associated and N is an integer from 0 to 31 identifying the
pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
PB31 is the last pin in GPIO port B. The jz4740 and the x1000 contains 4 GPIO
ports, PA to PD, for a total of 128 pins. The jz4760, the jz4770 and the jz4780
contains 6 GPIO ports, PA to PF, for a total of 192 pins.
