SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Fig. 85 Processor modes and ports P0 to P4
Note: The signal output disable select bit (bit 4 of the particular function select register 1) can stop the E signal output in the single-chip mode and the
φ1 output
in the microprocessor mode. In the memory expansion mode or the microprocessor mode, signal E can also be fixed to “H” when the internal memory
area is accessed.
