nored.

For a UART wake-up interrupt to occur, in addition to the

bits for the wake-up enable control and Receive inter-

rupt enable control being set, the global interrupt enable

control and the related interrupt enable control bits must

also be set. If these two bits are not set, then only a

wake-up event will occur and no interrupt will be ser-

viced. Note also that as it takes a period of delay after a

wake-up before normal microcontroller resumes, the

relevant UART interrupt will not be serviced until this pe-

riod of delay time has elapsed.
