Minimum period of initial A[25:0] address cycle; LDC[2:0] and HDC are asserted
and valid
Address A[25:0] outputs valid after CCLK falling edge

PUDC_B 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 PUDC_B input is Low.
Pin initially high-impedance (Hi-Z) if PUDC_B input is High.

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.
