JTAG Chain Device Removal Switch
The JTAG chain connects the Intel® Stratix® 10 TX FPGA, the MAX V CPLD, FMC in a chain, with the option to selectively bypass each JTAG node by four dip switch setting.
Program Select Pushbutton
If AvST configuration mode is selected, after a POWER-ON or RESET (reconfiguration) event, the MAX® V configures the Intel® Stratix® 10 TX FPGA if configuration mode is AvST mode with either the FACTORY POF or a USERDEFINED POF depending on FACTORY_LOAD setting. The setting of the PGMSEL bit is selected by the PGMSEL pushbutton. Pressing this pushbutton and observing the program LEDs (FACTORY or USER) dictates the program selection. Then, the PGM_CONFIG pushbutton must be pressed to load the program.
MAX® V Reset Pushbutton
This pushbutton is the development board's Master Reset. This pushbuttton is connected to the MAX® V CPLD (MAX_RESETn pin) that is used for AvST configuration. When this button is pressed, the MAX® V CPLD initiates a reloading of the stored image from flash memory using AvST configuration mode. The image that is reloaded depends on the PGMSEL setting.
CPU Reset Pushbutton
This pushbutton is the Nios® II CPU Reset. This button is connected to a Intel® Stratix® 10 TX FPGA global signal input pin and can be used by Nios® II implementations as a dedicated CPU Reset button. This button is also connected to the MAX® V CPLD so that the FPGA device can be reset right after its configuration with AvST mode.
