APPENDIX C PIN STATE IN EACH CPU STATE

APPENDIX C
Table C-1 to Table C-4 list the pin states in each CPU state.
■ Meaning of Terms in the Pin State Table
Terms related to the pin state have the following meanings:
• Input ready
Means that the input function can be used.
• Input 0 fixed
Input level is internally fixed at 0 to prevent leakage due to the input open.
• Output Hi-Z
Means that the pin drive transistor is disabled and the pin is set to high impedance.
• Output held
Means that the state output just before a mode is entered is output as is.
That is, if any built-in peripheral with output is active, the output is determined by the built-in
peripheral. For output as a port, the output is held.
• Preceding state held
Means that the state output just before a mode is entered is output as is. Also means input
ready if the state is the input state.
