User Pushbutton Switches

The ML605 provides six active-High pushbutton switches:

SW5, SW6, SW7, SW8 and SW9, arranged in a diamond configuration to depict “directional” headings North, South, East, West and Center respectively

SW10 CPU Reset pushbutton

The six pushbuttons all have the same active-High topology as the sample shown in Figure 1-19. The five directional pushbuttons are assigned as GPIO and the sixth is assigned as CPU_RESET. Figure 1-19and Table 1-22, page 50 describe the pushbutton switches.
