SCI interupts

Discussion created by ThirumalReddy Dhontham on May 16, 2012



In S12XEP100 controller , Im using SCI1 to SCI4 as LIN channels through transceiver MLX80001. When MCU is in STOP MODE, if only any one of the recieve edge interrupt is enabled and others disabled, then the MCU is coming out of stop mode with all the LIN channel interrupts.

Could anyone help me reason behing this behaviour as im expecting MCU to service interrupts from the channels only where the Rx edge interrupt is enabled ??


Thanks in advance..
