Figures 1-1, 1-2, and 1-3 show the block diagram, pin configuration and pin description, respectively, for the MAX1232. The IC is similar to that described for Figs. 1-K and 1-L, except that only '/to power is consumed. Figures 1-4 and 1-5 show the basic connections and waveforms, respectively, for the pushbutton reset.Figures 1-6 and 1-7 show the basic connections and waveforms, respectively, for watchdog timing. Notice that the software routine that strobes ST is critical. The code must be in a section of software that executes frequently enough so that the time between toggles is less than the watchdog timeout period, as shown in Fig. 1-7. Figures 1-8 and 1-9 show the power-down and power-up slew rate, respectively.Figures 1-10 and 1-11 show the VCC-detect reset-output delays.
