MINIT
<0:1:0>
HSWAP must be stable before INIT_B goes High and constant throughout the configuration process.
T
INITM
Pin initially pulled High by internal pull-up resistor if HSWAP input is Low.
Pin initially high-impedance (Hi-Z) if HSWAP input is High.

CCLK1

Mode input pins M[2:0] are sampled when INIT_B goes High. After this point,
input values do not matter until DONE goes High, at which point the mode pins
become user-I/O pins.
