Hi shweta:

MQX Lite handles all hardware interrupts as defined in the Interrupt Vector Table generated by PEx (see vector.c). Similary to standard MQX, MQX Lite provides a fisrt level ISR (kernel ISR), which is written in assembly language. The first level ISR runs before any other ISR.

MQX Lite provides a second level application ISRs that are coded as regualr functions and are installed into MQX Lite Interrupt Table through the Interrupt component API. Default second-level ISR for all possible interrupt sources is installed when MQX Lite starts. MQX Lite also supports the installation of user-specific, default, seconn-level ISR.

Please refer to the MQX Lite reference manual. Interrupt handling is described in section 2.1

Regards

Daniel
