Disconnects the board’s V50 source from pin 8 of the JTAG connector (VCC5).
Connects the board’s V50 source to pin 8 of the JTAG connector (VCC5) allowing the JTAG
connection to source the 5V power.
User Input Pushbuttons
The MAXQ610 EV kit board provides eight momentary
contact switches intended for user input. Each switch
is connected to a separate port pin on the MAXQ610’s
port 1 (P1.7–P1.0) as illustrated in Table 2 . The other
side of each switch is connected to ground. Therefore, by
using the weak pullup capability of the port pins, switch
closure can be detected by reading a low on the normally
high corresponding port pin.
