The Atmel CPLD Development/Programmer Board contains eight 8-segment LEDs to
allow the designer to observe the outputs of the ATF15xx. These eight LEDs are labeled
DSP1 to DSP8 on the board. These eight display LEDs are common anode LEDs with
the common anode lines connected to V
to the I/O pins of the ATF15xx CPLD on the CPLD Development/Programmer Board. To
turn on a particular segment of an LED, the corresponding ATF15xx I/O pin connected
to this LED segment must be in a logical-0 state. Hence, the outputs of the ATF15xx
need to be configured as active-low outputs in the design file.
Figure 2-2. 8-segment Display LED
Each segment of the display LED is hard-wired to one specific I/O pin of the ATF15xx.
For the higher pin count devices (100-lead and larger), all eight segments of the eight
LEDs are connected to the I/O pins of the ATF15xx. However, for the lower pin count
devices (84-lead and smaller), only a subset of the LED segments are connected to the
ATF15xx's I/O pins. Table 2-1 to Table 2-8 below show the connections of the LEDs to
the ATF15xx in all the different package types.
