GPIO PORT0 and PORT1 are ports accessible via either the group of registers
providing enhanced features and accelerated port access or the legacy group of
registers. PORT2/3/4 are accessed as fast ports only.
Accelerated GPIO functions:
– GPIO registers are relocated to the ARM local bus so that the fastest possible I/O
timing can be achieved.
