3.15 MAM.1: Under certain conditions in MAM Mode 2 code execution out
of internal flash can fail
Introduction:
The MAM block maximizes the performance of the ARM processor when it is running
code in flash memory. It includes three 128-bit buffers called the Prefetch Buffer, the
Branch Trail Buffer and the data buffer. It can operate in 3 modes; Mode 0 (MAM off),
Mode 1 (MAM partially enabled) and Mode 2 (MAM fully enabled).
Problem:
Under certain conditions when the MAM is fully enabled (Mode 2) code execution from
internal flash can fail. The conditions under which the problem can occur is dependent on
the code itself along with its positioning within the flash memory.
Work-around:
If the above problem is encountered then Mode 2 should not be used. Instead, partially
enable the MAM using Mode 1.
3.16 CAN.1: Data Overrun condition can lock the CAN controller
Introduction:
Each CAN controller provides a double Receive Buffer (RBX) per CAN channel to store
incoming messages until they are processed by the CPU. Software task should read and
save received data as soon as a message reception is signaled.
In cases where both receive buffers are filled and the contents are not read before the
third message comes in, a CAN Data Overrun situation is signaled. This condition is
signaled via the Status register and the Data Overrun Interrupt (if enabled).
Problem:
In a Data Overrun condition, the CAN controller is locked from further message reception.
Work-around:
1. Recovering from this situation is only possible with a soft reset to the CAN controller.
2. If software cannot read all messages in time before a third message comes in, it is
recommend to change the acceptance filtering by adding further acceptance filter
group(s) for messages, which are normally rejected. With this approach, the third
incoming message is accepted and the Data Overrun condition is avoided. These
additional messages are received with the corresponding group index number can be
easily identified and rejected by software.
