Configuration Push Button

The configuration push button, PGM1_CONFIG (S3), is an input to the MAX

II CPLD

EPM2210 System Controller. The push button forces a reconfiguration of the FPGA
from flash memory. The location in the flash memory is based on the settings of the
PGM1_LED[2:0]

, which is controlled by the image select push button, PGM1_SEL (S2).

Valid settings include PGM1_LED0, PGM1_LED1, or PGM1_LED2 on the three pages in flash
memory reserved for FPGA designs.

Table 2–19

lists the configuration push button component reference and

manufacturing information.

Image Select Push Button

The program select push button, PGM1_SEL (S2), is an input to the MAX II CPLD
System Controller. The push button toggles the PGM1_LED[2:0]sequence that selects
which location in the flash memory is used to configure the FPGA. Refer to

Table 2–8

for the PGM1_LED[2:0] sequence definitions.

Table 2–20

lists the image select push button component reference and manufacturing

information.
