REGISTERS
The general behavior of registers is as follows:
All registers are 0 on reset.
All registers are read/write unless otherwise specified.
Unused bits are read as 0.
Interrupt bits are cleared by writing 1 to the flag; writing 0
or reading the flag has no effect, with the exception of the
key press, key release, and GPIO interrupt status registers,
which are cleared on a read.
