Slave Serial Mode Programming Switching Characteristics
Notes: 1. The max limit of CCLK Low time is caused by dynamic circuitry inside the LCA device.
2. Configuration must be delayed until the INIT of all LCA devices is High.
3. At power-up, V
CC
must rise from 2.0 V to V
CC
min in less than 25 ms. If this is not possible, configuration can be de-
layed by holding RESET Low until V
CC
has reached 4.0 V (2.5 V for the XC3000L). A very long V
CC
rise time of >100
ms, or a non-monotonically rising V
CC
may require a >6-
μ
s High level on RESET, followed by a >6-
μ
s Low level on
RESET and D/P after V
CC
has reached 4.0 V (2.5 V for the XC3000L).

Notes: 1. During Readback, CCLK frequency may not exceed 1 MHz.
2. RETRIG (M0 positive transition) shall not be done until after one clock following active I/O pins.
3. Readback should not be initiated until configuration is complete.
