1.2 Recommended Connection for Unused Pins
Notes 1.
Can leave open, if no access to external data memory is
executed in the whole of program.
But in the HALT 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 when the current consumption is
reduced, connect a pin as recommended connection.
