DESCRIPTION:
During a UART TX interrupt, if the IIR register is read and the THR register is not written to (to clear the TX interrupt), the UART TX interrupt
is masked. This can happen in an ISR if the end of the string is reached. In this case, disabling and enabling the ETBEI bit has no effect on
the state of the interrupt enable, but it should.
WORKAROUND:
Clear the ETBEI bit within the UART TX interrupt to end a string, and then execute an RTI. To re-enable the interrupt, simply set the ETBEI
bit. This will take the processor directly into the UART TX interrupt service routine when the THR register is empty.
APPLIES TO REVISION(S):
0.3, 0.4
DESCRIPTION:
If the NMI pin is asserted at boot time, the boot process will fail because there is no handler in the boot ROM. The behavior is not
predictable.
WORKAROUND:
Do not assert the NMI pin during a boot sequence.
APPLIES TO REVISION(S):
0.3, 0.4, 0.5, 0.6
DESCRIPTION:
The duration of the start-bit in a word transmitted by the UART interface is incorrect.
For Clock Divisor values greater than 1 (as determined by the UART_DLL and UART_DLH registers), the pulse width can assume values of
14/16th or 15/16th of the nominal bit time.
Data, Parity and Stop bits have proper duration. The data will be correctly received.
See anomalies 05000230 and 05000231 regarding UART timing.
WORKAROUND:
None
APPLIES TO REVISION(S):
0.3, 0.4
