DATA_LEN_CNT (DATALENCNT_0): This field is used to indicate the size 
of the data to be transferred. Reset default = 0h. For write operations, this 
field is set by software to indicate to the hardware how many bytes of data in 
Data Buffer are to be transferred to the console. A value of 0h indicates that 
a zero-length packet should be sent. A value of 1-8 indicates 1-8 bytes are to 
be transferred. Values 9-Fh are illegal and how hardware behaves if used is 
undefined. For read operations, this field is set by hardware to indicate to 
software how many bytes in Data Buffer are valid in response to a read 
operation. A value of 0h indicates that a zero length packet was returned and 
the state of Data Buffer is not defined. A value of 1-8 indicates 1-8 bytes 
were received. Hardware is not allowed to return values 9-Fh. The 
transferring of data always starts with byte 0 in the data area and moves 
toward byte 7 until the transfer size is reached.
