Note 62: This feature is only available if one of the packages T-QFP-64 or
The S/G bit status information will be additionally provided on pin SG (see
"Miscellaneous Function Pins", page 46).
Figure 89
Note that in state number 6 of the S/G bit control state machine (see Figure 86, page
201) the S/G bit is not defined. In this case the polarity of pin SG may differ from the
polarity of the S/G bit on IOM
For timing properties see "Timing Properties of Pin SG in TE Mode", page 286.
