NOTES:
1. The Full Flag is asserted in the Serial-ln mode by using the t
SICFF
parameter. This parameter is measured in the worst case condition from the rising
edge of SICP following a (t
PD1
+t
WFF
) delay from the first SICP rising edge of the last word.
2. First Read rising edge after
FF
is set.
3. After
FF
goes LOW and the last bit of the final word has been clocked in, SICP should not be clocked until
FF
goes HIGH.
Figure 23. Full Flag and Full-1 Flag Assertlon in the Serial-ln Mode (FIFO Being Filled)
NOTES:
1. The FIFO is full and a new read sequence is started.
2. On the first rising edge of SOCP, the
FF
is de-asserted. In the Serial-ln mode, a new write operation can begin following t
RFFS1
after
FF
, goes HIGH.
In the Parallel-ln mode, a new write operation can occur immediately after
FF
goes HIGH.
3. The
FF-1
flag is de-asserted after the first SOCP of the second serial word.
