External BusesMitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER___________________5.6 Releasing an External Bus (HOLD input and HLDA output)The Hold feature is to relinquish the address bus, the data bus, and the control bus on M16C/62 side in linewith the Hold request from the bus master other than M16C/62 when the two or more bus masters share theaddress bus, the data bus, and the control bus. The Hold feature is effective only in memory expansionmode and microprocessor mode.The sequence of using the Hold feature may be:__________1. The external bus master turns the input level of the HOLD terminal to “L”.2. When M16C/62 becomes ready to relinquish buses, each bus becomes high-impedance state at thefalling edge of BCLK.__________3. The HLDA terminal becomes “L” at the rising edge of the next BCLK.4. The external bus master uses a bus.5. When the external bus master finishes using a bus, the external bus master returns the input level of__________the HOLD terminal to “H”.__________6. The output from HLDA terminal becomes “H” at the rising edge of the next BCLK.7. Each bus returns from the high-impedance state to the former state at the rising edge of the nextBCLK.__________As given above, each bus invariably gets in the high-impedance state while the HLDA output is “L”. Also,M16C/62 doesn't relinquish buses during a bus cycle. That is, if a Hold request comes in during a bus cycle,__________the HLDA output become “L” after that bus cycle finishes.In the Hold state, the state of each terminal becomes as follows.• Address bus A0 to A19High-impedance state. The case in which A16 to A19 are used as ports P40 to P43 (64K byte addressspace) and the case in which A9 to A19 are used as ports P31 to P37 and P40 to P43 (multiplex for thewhole area) in microprocessor mode too fall under this category.• Data bus D0 to D15High-impedance state. The case in which D8 to D15 are used as ports P10 to P17 (8-bit external buswidth) and the case in which D0 to D15 are used as ports P00 to P07 and P10 to P17 (multiplex for thewhole area) in microprocessor mode too fall under this category._____ ______ ________ _________ ________• RD, WR, WRL, WRH, BHEHigh-impedance state.• ALEAn internal clock signal having the same phase as BCLK is output._______ _______• CS0 to CS3High-impedance state. The case in which ports are selected by the chip selection control register toofalls under this category.Figure. 5.6.1 shows an example of relinquishing external buses.540
