GPIO Subsystem Register Descriptions
6.16.2.20 GPIO/AUX Lock Enable (GPIO[x]_LOCK_EN
These registers lock the values of feature bit registers except the GPIO[x]_READ_BACK, GPIO[x]_IN_POSEDGE_STS,
and GPIO[x]_IN_NEGEDGE_STS registers. When set, the indicated feature bits may not be changed. The
GPIO[x]_LOCK_EN registers are not based on the atomic programming model (i.e., only one bit for control as opposed to
two bits).
