1.2.3 BeMicroSDK Switches
There are five switches on the BeMicroSDK: three push-button switches and two slide
switches. See Figure 7 for switch locations.
1.2.3.1 Push-button Switches (S502
– S504)
The bottom push-
button switch (S502), labeled “RECFG”, is used to force an FPGA
reconfiguration. When this switch is pressed, the FPGA is reloaded from the on-board
flash memory and restarts in the same manner as a power-on reset.
The middle push-
button switch (S503), labeled “Reset”, is used to reset the FPGA logic
and internal soft-core CPU. Note that this does not cause a reconfiguration; it merely
restarts the FPGA logic from a known reset state.
The top push-
button switch (S504), labeled “User”, can be read by the FPGA firmware.
This switch is not currently used.
