OMAP L137 EVM MCASP DSP ISR

Hi, I'm working with the starter kit OMAP L137 EVM. Continuing the implementation of aic3106 test, which reproduces a sinusoid by the output channel and record the input channel.
The problem I have is that I want to mount a real-time system in which, instead of waiting until the buffer is ready to transmit, would it generates an interrupt when transmitting.
I found that this can be done through the McASP XINTCTL and RINTCTL records but can not find in the documentation the "vector" necessary to activate the interrupt service routine (ISR).
Could anyone help me with this?
