2.8.3 Occurrence of Fetch Error

When at least one channel using linked descriptors is already active, a channel Fetch Error (FERR) may occur on enabling a channel with no linked descriptor or when one of the already active channels using linked descriptors may fetch the enabled second descriptor (index 1) of the channel. These errors can occur when a channel is enabled during the link request of another channel and if the channel number of the enabled channel is lower than the already active channel.
