1.5 Device Reset Options
The power-on reset, RapidConfigure reset, hardware reset, and JTAG reset functions will program the
output buffers to flow-through mode (with Global Clock selected), and Output Enabled (ON). JTAG can
be reset via the TRST# pin or by clocking five consecutive one to the TMS pin. The hardware reset pin
can be done accomplished through the HW_RST# pin (active low). RC reset can be accomplished by
applying the RC instruction 1101 to the RCI[3:0] pins.
