Detailed Description
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 1-19 and Table 1-22, page 50 describe the pushbutton switches.
