Hardware Reset.
RapidConfigure Mode Select
Programing mode is determined at power up or HW_RST
0 = JTAG Mode (RapidConfigure Disabled)
1 = RapidConfigure Mode (JTAG, I/O buffer, Crosspoint Programming Disabled)
Note: Device can be reconfigured from JTAG to RC or from RC to JTAG in the JTAG mode without HW_RST or power
up. In RapidConfigure mode the programming of the I/O buffers and crosspoint array through JTAG is disabled, but the
JTAG port can still be used for boundary scan testing.
