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.
