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.
