1.The VCCINT, VCCAUX, and VCCO supplies can be applied in any order.

2.The Low-going pulse on PROG_B is optional after power-on but necessary for reconfiguration without a power cycle.

3.The rising edge of INIT_B samples the voltage levels applied to the mode pins (M0 - M2).

TINIT	Minimum Low pulse width on INIT_B output	All	300	-	ns
TICCK(3)	The time from the rising edge of the INIT_B pin to the	All	0.5	4	μs

	output pin

Notes:

1.The numbers in this table are based on the operating conditions set forth in Table 7. This means power must be applied to all VCCINT, VCCO, and VCCAUX lines.

2.Power-on reset and the clearing of configuration memory occurs during this period.

3.This specification applies only to the Master Serial, SPI, and BPI modes.
