Functional Description
JTAG
JTAG signals routed directly through the CPLD to FPGA. Access between CPLD and FPGA can be multiplexed via JTAGEN (logical one for CPLD, logical zero for FPGA).
Power
PGOOD is zero, if EN1 or PG_SENSE is zero else high impedance state.
FPGA Configuration
FPGA configuration process will be stared, if RESIN, PG_SENSE and EN1 is ONE.
