Signaling Interface Timing
8.8.1
Timing from the
μ
C Interface to the SO/SB-pins
Figure 32
Signaling Output Timing (data downstream)
8.8.2
Timing from the SI/SB-pins to the
μ
C Interface
The register update and interrupt behavior resulting from signaling input changes (data
upstream
pins SI and SB, if programmed as signaling inputs) depend on internal
sampling clocks, counters and register settings. See
Chapter 5.3.2
for a functional
description.
