Figure 11 - Output Test Load
Timing is over recommended temperature & power supply voltages
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
* Contents of Connection Memory are not lost if the clock stops, however, ST-BUS outputs go into the high impedance state.
NB:
Frame Pulse is repeated every 512 cycles of C4i.
