TRIGGER CONDITION(S)
The asynchronous Rx/Tx clock source IMO frequency tolerance may deviate beyond the data sheet limit of
±2.5% when operated beyond the temperature range of 0 to +70°C.
■
SCOPE OF IMPACT
This problem may affect UART, IrDA, and FSK implementations.
■
WORKAROUND
Implement a quartz crystal stabilized clock source on at least one end of the asynchronous digital
communications interface.
■
FIX STATUS
The cause of this problem and its solution has been identified. Silicon fix is planned to correct the deficiency
in silicon.
