50. SAM9263 Errata
50.1 SAM9263 Errata - Revision “B” Parts
50.1.1 Main Oscillator
50.1.1.1 Main Oscillator: Spurious Malfunction of Main Oscillator
The main oscillator can exhibit spurious malfunction as exhibited by the duty-cycle not performing according to
specification, missing main clock periods, or in the worst case, no main clock at all. The behavior does not alter
over time. A device fully tested over the operating range (including power supply and temperature) in an
application without exhibiting any malfunction will continue to function according to specifications.
Problem Fix/Workaround
Placing a series resistor of 470 Ω between XOUT and the crystal will fix the issue.
The additional series resistor will not alter the device specification as documented in the datasheet, including the
startup time and power consumption.
50.1.2 Two D Graphic Controller (TDGC)
50.1.2.1 Polygon Fill Function
Polygon fill function is not functional.
Problem Fix/Workaround
None.
50.1.2.2 TDGC Clipping Function
The Clipping function is not functional.
Problem Fix/Workaround
None.
50.1.3 AC97
50.1.3.1 Bad Management of Endianness Conversion
When the transfer size is not a multiple of bytes, the Endianness is incorrect.
Problem Fix/Workaround
None.
50.1.4 Bus Matrix
50.1.4.1 Problem with Locked Transfers
Locked transfers are not correctly handled by the Bus Matrix and can lead to a system freeze-up.
This does not concern ARM locked transfers.
Problem Fix/Workaround
Avoid other Bus Matrix masters locked transfers.
