5.7 Precautions for External Bus
(1) The external ROM version can operate only in the microprocessor mode, so be sure to per-
form the following:
• Connect the CNVSS pin to Vcc.
• Fix the processor mode bits (b1 and b0) to “112”.
(1) An “L” level is input to the HOLD pin.
(2) HOLD is detected.
(3) The CPU releases the bus.
(4) An “L” is output to the HLDA pin.
(5) An “H” is input to the HOLD pin.
(6) An “H” is output to the HLDA pin.
(7) The CPU not releases the bus.
(8) The CPU resumes using the bus.
