The pin assignment listed in Table 2 to Table 4 refers to the corresponding
in combination with the MBa65xx.
The electrical and pin characteristics are to be taken from the AM65xx Data Sheet (1), and the AM65xx Reference Manual (2).

Depending on the configuration, many AM65xx balls can provide several different functions.
Please take note of the information in the AM65xx Reference Manual (2), and the AM65xx Errata (3)
concerning the configuration of these pins before integration or start-up of your carrier board.
Improper programming by operating software can cause malfunctions, deterioration or destruction
of the TQMa65xx. Pins marked with “NC” must never be connected and have to be left open.
