The McASP includes error-checking capability for the serial protocol and data underrun. In addition, the McASP includes a timer that continually measures the high-frequency master clock every 32 AHCLKX clock cycles. The value of the timer can be read to get a measurement of the clock frequency and has a minimum and maximum range setting that can set an error flag if the master clock goes out of a specified range.
When one or more errors (software selectable) are detected, an interrupt can be generated if desired, based on one or more error sources.
