0	0h	RW	Pad Config Lock (PADCFGLOCK_GPP_I_0) PadCfgLock locks specific register fields in the pad specific registers (in Community or Pad) from being configured. The registers affected become Read-Only and software writes to these registers have no effect. This field is meaningful and takes effect only if the pad is owned by host (refer to PAD_OWN register). Pads under other ownership are not affected by the PadCfgLock. 0 = Unlock 1 = Lock the following register fields as read-only (RO): - Pad Configuration registers (exclude GPIOTXState) - GPI_NMI_EN Register (if implemented) - HOSTSW_OWN Registers (if implemented)
