TMP89FM42
RA005
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,
m=1 to 0, n=3 to 0)
Note 1: When the key-on wakeup input (KWIi) is enabled, there is no need to set P4FCi.

The built-in pull-up resistor is not connected.
1:
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 con-
nected.)
