Hardware Description

Configuration from the DEV CHIP RECONFIG pushbutton

FPGA registers SYS_CFGDATA1 and SYS_CFGDATA2 contain configuration data that is applied to the ARM926EJ-S PXP Development Chip when the DEV CHIP RECONFIG pushbutton is pressed.

When nPBSDCREFCONFIG is asserted, the configuration values stored in the FPGA configuration registers are output to the development chip data bus (HDATAM1 and HDATAM2) pins.
