Electrical Characteristics
(continued)
Note: The requirements in this timing diagram are extremely relaxed; data need not be held beyond the rising edge of
WS
.
BUSY
will go active
within 60 ns after the end of
WS
.
BUSY
will stay active for several microseconds.
WS
may be asserted immediately after the end of
BUSY
.
Figure 38. Peripheral Mode Switching Characteristics
Notes:
At powerup, V
CC
must rise from 2.0 V to V
CC
minimum in less than 25 ms. If this is not possible, configuration can be delayed by holding
RESET
low until V
CC
has reached 4.0 V. A very long V
CC
rise time of >100 ms, or a nonmonotonically rising V
CC
may require a >1 μs high level on
RESET
, followed by >6 μs low level on
RESET
and D/
P
after V
CC
has reached 4.0 V.
Configuration must be delayed until the
INIT
of all FPGAs is high.
Time from end of
WS
to CCLK cycle for the new byte of data depends on completion of previous byte processing and the phase of the
internal timing generator for CCLK.
CCLK and DOUT timing is tested in slave mode.
T
BUSY
indicates that the double-buffered parallel-to-serial converter is not yet ready to receive new data. The shortest T
BUSY
occurs when a
byte is loaded into an empty parallel-to-serial converter. The longest T
BUSY
occurs when a new word is loaded into the input register before the
second-level buffer has started shifting out data.
