Note 1: Symbol "I" means secondary function input.
Note 2: When the key-on wakeup input (KWIi) is enabled (KWUCRm<KWnEN>="1"), there is no need to set P4CRi. (i=7 to 0,

Port function
The built-in pull-up resistor is not connected.
The built-in pull-up resistor is connected.
(The resistor is connected only when the key-on wakeup input (KWIi) is enabled or the port is used in the input mode
(P4FCi="0" and P4CRi="0"). Under any other conditions, setting to "1" does not make the resistor connected.)
If the port is in the input mode, the contents of the port are read. If not, "0" is read.
