8.4.4 GPIO port output Set register (IOSET, Port 0: IO0SET - 0xE002 8004
and Port 1: IO1SET - 0xE002 8014; FIOSET, Port 0: FIO0SET -
0x3FFF C018 and Port 1: FIO1SET - 0x3FFF C038)
This register is used to produce a HIGH level output at the port pins configured as GPIO in
an OUTPUT mode. Writing 1 produces a HIGH level at the corresponding port pins.
Writing 0 has no effect. If any pin is configured as an input or a secondary function, writing
1 to the corresponding bit in the IOSET has no effect.
Reading the IOSET register returns the value of this register, as determined by previous
writes to IOSET and IOCLR (or IOPIN as noted above). This value does not reflect the
effect of any outside world influence on the I/O pins.
