CHAPTER 3 CPU
3.5.4 State of Each Pin at Reset
The state of each pin is initialized by a reset.
States of Pins during Reset
When a reset occurs, most I/O pins (resource pins) become Hi-Z, and the CPU reads the mode data from
internal ROM.
States of Pins after the CPU Reads the Mode Data
Most of the I/O pins remain Hi-Z immediately after the CPU reads the mode data.
For pin states established by something other than a reset, see "APPENDIX E Pin State of the MB89202/
F202RA Series " for details.
Note:
For pins that are Hi-Z when a reset source is generated, set up the devices connected with the pins such
that they do not malfunction.
