Figure 329. SDIO adapter command path

• Command path state machine (CPSM)

– When the command register is written to and the enable bit is set, command

transfer starts. When the command has been sent, the command path state

machine (CPSM) sets the status flags and enters the Idle state if a response is not

required. If a response is required, it waits for the response (see Figure 330 on

page 1018). When the response is received, the received CRC code and the

internally generated code are compared, and the appropriate status flags are set.
