// Contains constants relevant to the Altera Virtual JTAG

// device, which are not included in the BSDL.

// As of this writing, these are constant across every

// device which supports virtual JTAG.

// These are commands for the FPGA's IR

#define ALTERA_CYCLONE_CMD_VDR     0x0C

// These defines are for the virtual IR (not the FPGA's)

// The virtual TAP was defined in hardware to match the OpenCores native

// TAP in both IR size and DEBUG command.
