Notes 1.
These pins may be left unconnected if the external data memory is not accessed in the program.
However, connect these pins as recommended in the halt and stop modes when the power
consumption must be lowered.
2.
These pins may be left unconnected if HCS, HRD, and HWR are fixed to the high level.
However, connect these pins as recommended in the halt and stop modes when the power
consumption must be lowered.
