+1 T_STx
Note The one-shot time can be changed. For details, refer to the one-shot time set-
tings for the top/valley hold function.
The Analog Status Flags include allocations for the Comparator Result Flag,
the Top/Valley Detection Timing Flags, and the Off-wire Detection Flags.
These flags are used for detection and monitoring.
The data format used for each byte when these flags are allocated in the Mas-
ter is shown below (2 bytes/1 word).
