F16o
Frame Pulse ST-BUS 16.384Mb/s (CMO7S Output).
This is an 8kHz 61ns active low
framing pulse, which marks the beginning of an ST-BUS frame. This is typically used for
ST-BUS operation at 16.384Mb/s. See Figure 11.

F0o
Frame Pulse ST-BUS 2.048Mb/s (CMOS Output).
This is an 8kHz 244ns active low
framing pulse, which marks the beginning of an ST-BUS frame. This is typically used for
ST-BUS operation at 2.048Mb/s and 4.096Mb/s. See Figure 11.
10
F8o
Frame Pulse ST-BUS 8.192Mb/s (CMOS Output).
This is an 8kHz 122ns active high
framing pulse, which marks the beginning of an ST-BUS frame. This is used for ST-BUS
operation at 8.192Mb/s. See Figure 11.
