When GPIO1 is configured as output and Register h74 bit[0] = 0 (default), the
value of this register will be placed on the GPIO1 pad.
When GPIO1 is configured as output and Register h74 bit[0] = 1, the GPIO1 pad
will get its value from slot12.
When GPIO1 is configured as input and configured as a sticky writing a 1 does
nothing, writing a 0 clears this bit.
When GPIO1 is configured as input this register reflects the value on the GPIO1
pad after interpretation of the polarity and sticky configurations.
When GPIO0 is configured as output and Register h74 bit[0] = 0 (default), the
value of this register will be placed on the GPIO0 pad.
When GPIO0 is configured as output and Register h74 bit[0] = 1, the GPIO0 pad
will get its value from slot12.
When GPIO0 is configured as input and configured as a sticky writing a 1 does
nothing, writing a 0 clears this bit.
When GPIO0 is configured as input this register reflects the value on the GPIO0
pad after interpretation of the polarity and sticky configurations.
