Notes 1. Can leave open, if no access to external data memory is

executed in the whole of program.

But in the HALT mode or STOP mode when the current

consumption is reduced, connect a pin as recommended

connection.

2. Can leave open, if HCS, HRD, HWR are fixed to high level.

But in the HALT mode or STOP mode when the current

consumption is reduced, connect a pin as recommended

connection.

Remark I: Input pin, O: Output pin, I/O: Input/Output pin
