2.9 Error Behavior
indicated for each operating mode. Note that for high sample rates with more than
four channels (96 kHz, 32-bit, >4ch), Audio Out cannot guarantee error-free operation
due to data bus latency restrictions.
Table 6: Audio Out Latency Tolerance Examples
In normal operation, the system controller and Audio Out hardware continuously
exchange buffers without ever failing to transmit a sample. If the system controller
fails to provide a new DMA buffer address in time, the UNDERRUN error flag is raised
and the last valid sample or sample pair is repeated until a new buffer of data is
assigned by an ACK1 or ACK2. The UNDERRUN flag is not affected by ACK1 or
ACK2; it can only be cleared by an explicit ACK_UDR.
