3.6 SD Bus Topology 
The SD bus has six communication lines and two supply lines: 
‧ 
CMD: Command is bi-directional signal. (Host and card drivers are operating in push pull mode.)   
‧ 
DAT0-3: Data lines are bi-directional signals. (Host and card drivers are operating in push pull mode.) 
‧ 
CLK: Clock is a host to cards signal. (CLK operates in push pull mode.) 
‧ 
VDD: VDD is the power supply line for all cards. 
‧ 
VSS: VSS are two ground lines. 
The following figure shows the bus topology of several cards with one host in SD Bus mode.
