The JTAG fuse/Onchip debug disable is very important for power-down/sleep
modes. If these "fuses" are on/enabled, the minimum sleep current will be
approx 3mA (x300 higher than you want!)

uisp <progammer parameters...> -wr_fuse_h=0xD9
disables the JTAG fuse.

uisp <programmer parameters..> -wr_fuse_h=0x19
enables the JTAG fuse

You use JTAG fuse for debugging with Atmel's JTAG pod and ice-insight...
