(1) X = Don't care
(2) Setting P7SEL.0 causes the general-purpose I/O to be disabled. Pending the setting of XT1BYPASS, P7.0 is configured for crystal mode or bypass mode.
(3) Setting P7SEL.0 causes the general-purpose I/O to be disabled in crystal mode. When using bypass mode, P7.1 can be used as general-purpose I/O.
