Atmel CPLD Development/Programmer Board contains eight push-button switches,
which are connected to the I/O pins of the CPLD. They allow designers to send input
logic signals to the user I/O pins of the ATF15xx CPLD. These eight switches are
labeled SW1 to SW8 on the Atmel CPLD Development/Programmer Board. One end of
each input push-button switch is connected to VCCIO while the other end of each push-
button switch is connected to a pull-down resistor and then connected to the specific I/O
pin of the CPLD through the JPS1/JPS2/JPS3/JPS4/JPS5/JPS6/JPS7/JPS8 selectable
jumper.
If any one of these switches is pressed and the corresponding jumper is set, the specific
I/O pin of the device will be driven to a logic high state by the output of switch circuit.
Since each push-button switch is also connected to a pull-down resistor, the input will
have a logic low state if the switch is not pressed with the corresponding jumper set. If
the push-button jumper is not set, the corresponding pin will be treated as an uncon-
nected pin. Figure 2-4 on page 2-7 is a circuit diagram of the push-button switch and
selectable jumper. Tables 2-9, 2-10, 2-11, and 2-12 show the connections of these eight
push-button switches to the CPLD I/O pins in the different package types.
