Factory test scan chain provision
Table 60
Signals provided for factory test scan chain control
In normal use factory test scan chain control pins must be not connected or kept LOW. If any of these pins are pulled
HIGH in the application, damage to the SAA2502 and/or the surrounding components may occur.
8.1.4.5
Provision to read internal status
The following internal status information is made available for reading. It provides designers additional information on
status and/or progress of internal processes. This information has no meaning for the application.
