Power-Down and Sleep Mode Implementation
VJTAG and VPP should be connected to ground during Power-Down and Sleep modes. Note that when
VJTAG is not powered, the 1.5 V voltage regulator cannot be enabled through TRSTB.
VPP and VJTAG can be controlled through an external switch. Actel recommends ADG839, ADG849, or
ADG841 as possible switches.
the switch can be connected to PTBASE of the SmartFusion device. VJTAG can be controlled in same
manner.
