Notes 1.
Circled characters indicate the Schmitt-trigger input.
2.
If on-chip pull-up resistors are not specified by mask option (when used as N-ch open-drain input
port), low level input leakage current increases when input or bit manipulation instruction is executed.
High level
(when pull-up
resistors are
provided) or
high-
impedance
