Table 9.9 Pin Status in Stop Mode Pin Memory Expansion Mode(1) Single-Chip Mode Microprocessor Mode(1) _______ _______ _______ Address Bus, Data Bus, CS0 to CS3, BHE Maintains state immediately before entering stop mode _____ ______ ________ _________ RD, WR, WRL, WRH "H" __________ HLDA, BCLK "H" ALE "H" Ports Maintains state immediately before entering stop mode CLKOUT When fC selected "H" When f8, f32 selected Maintains state immediately before entering stop mode XIN Placed in a high-impedance state XOUT "H" XCIN, XCOUT Placed in a high-impedance state NOTES: 1. M32C/86T cannot be used in memory expansion mode and microprocessor mode. |
