Instead of this count wrapping at the buffer size, it now increments continuously. The offset within the buffer is now obtained from the lower bits of the count. This makes it possible to keep track of the total number of bytes transferred by the M0 core. The count will wrap at 2^32 bytes, which at 20Msps will occur every 107 seconds.
