5.7
There is no way specifying the time when data applied to SI-pins (and SB-pins if
programmed as signaling input pins) is sampled by the PEB 2466.
The time only depends on internal signals (16 MHz masterclock, and status of various
counters), and there is no link to a low frequency external signal.
From the SI/SB-pins to the
μ
C-interface (data upstream)
1)
All delay times are made up by two components: an intrinsic time (min-time), caused by internal processings,
and a second component caused by external circuitry (C-load)
