Note:P0CR1 and P0CR0 must be clear to "0".
Note 1: When SYSCR2<XEN> is "1", setting P0FC0 to "0" generates a system clock (internal factor) reset. Normally, ports P00
Note 2: Symbol "I" means secondary function input

The built-in pull-up resistor is not connected.
The built-in pull-up resistor is connected. (The resistor is
connected in the input mode only. Under any other con-
ditions, setting to "1" does not make the resistor connec-
ted.)
