Detailed Description

User Pushbutton Switches

The SP605 provides five active-High pushbutton switches: SW4, SW5, SW6, SW7 and SW8.

The five pushbuttons all have the same topology as the sample shown in Figure 1-16. Four

pushbuttons are assigned as GPIO, and the fifth is assigned as a CPU_RESET. Figure 1-16

and Table 1-24 describe the pushbutton switches.
