Notes:
1. At power-up, VCC must rise from 2.0 V to VCC min in less than 25 ms. If this is not possible, configuration can be delayed by
holding RESET Low until VCC has reached 4.0 V (2.5 V for the XC3000L). A very long VCC rise time of >100 ms, or a
non-monotonically rising VCC may require a >6-s High level on RESET, followed by a >6-s Low level on RESET and D/P
after VCC has reached 4.0 V (2.5 V for the XC3000L).
2. Configuration can be controlled by holding RESET Low with or until after the INIT of all daisy-chain slave-mode devices is
High.
This timing diagram shows that the EPROM requirements are extremely relaxed:
EPROM access time can be longer than 4000 ns. EPROM data output has no hold time requirements.
