Configuration Push-button Switches

The PGM configure push-button switch, PGM_CONFIG (S8), is an input to the MAX II
CPLD EPM2210 System Controller. The push-button switch forces a reconfiguration
of the FPGA from flash memory. The location in the flash memory is based on the
PGM_LED[2:0] setting when the button is released. Valid settings include
PGM_LED0, PGM_LED1, or PGM_LED2 illuminated. There are three pages in flash
memory reserved for FPGA designs.
The PGM select push-button switch, PGM_SEL (S9), toggles the program LEDs (D29,
D30, D31) sequence. Refer to
definitions.
The CPU reset push-button switch, CPU_RESETn (S2) is a dedicated reset switch for
the embedded processors which is wired to the FPGA DEV_CLRn pin, while the MAX
II reset push-button switch, MAX_RESETn (S10), resets the MAX II CPLD EPM2210
System Controller.
