@deffn {Command} {virtex2 read_stat} num
Reads and displays the Virtex-II status register (STAT)
for FPGA @var{num}.

@deffn {FPGA Driver} {lattice} [family]
The FGPA families ECP2 and ECP3 by Lattice are supported.
This driver can be used to load the bitstream into the FPGA or read the status register and read/write the usercode register.
The option @option{family} is one of @var{ecp2 ecp3}. This is needed when the JTAG ID of the device is not known by openocd (newer NX devices).
@deffn {Command} {lattice read_status} num
Reads and displays the status register
for FPGA @var{num}.
@end deffn
@deffn {Command} {lattice read_user} num
Reads and displays the user register
for FPGA @var{num}.
@end deffn
@deffn {Command} {lattice write_user} num val
Writes the user register.
for FPGA @var{num} with value @var{val}.
@end deffn
@deffn {Command} {lattice set_preload} num length
Set the length of the register for the preload. This is needed when the JTAG ID of the device is not known by openocd (newer NX devices).
The load command for the FPGA @var{num} will use a length for the preload of @var{length}.
