Following is an example of a C program that shows how to write data into the ATL
buffer RAM. The total number of data bytes to be transferred is 80 (decimal) that will
be set into the HcTransferCounter register as 50H. The data consists of four types of
PTD data:
In all PTDs, we have assigned device address as 5 and endpoint as 1. ActualBytes is
always zero (0). TotalBytes equals the number of payload data bytes transferred,
however, note that for bulk and control transfers, TotalBytes can be greater than
MaxPacketSize.
