Note:When P0FC0 is set to "1" (XIN(I) is selected as function), P0CR1 and P0CR0 must be clear to "0".If P0CR0
or P0CR1 is set to "1" while P0FC0 is "1" then the output of oscillation port will be short and Operation cur-
rent will increase.

Note 1: To select the external high-freuency clock,the setting"1"to P0FC0 should be done before SYSCR2<XEN> is set to
"1"when P0FC0 is "0",the setting"1"to SYSCR2<XEN>generates a system clock(internal factor)reset.
Note 2: Symbol"I"means secondary function input

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