6.16.1
The registers in Section 6.16.2 "GPIO Low/High Bank Feature Bit Registers", starting on page 456, that are referred to as
“atomic” all follow the same programming model (i.e., work exactly the same way) but each controls a different GPIO fea-
ture. Two data bits are used to control each GPIO Feature bit, each pair of bits operate in an exclusive-OR pattern. Refer to
Section 5.15.2 "Register Strategy" on page 161 for further details.
The Low Bank registers control programming of GPIO15 through GPIO0 and the High Bank registers program GPIO31
through GPIO16. The tables that follow provide the register/bit formats for the Low and High Bank GPIO feature configura-
tion registers.
Note: All register bits dealing with GPIO31, GPIO30, GPIO29 and GPIO23 are Reserved .
