13.2.2.6.4 Simple Commands

To send a command with no data to the slave, the master does the following:

  1. Sends a POLL command and verifies that the slave is ready (no RXBUSY from Table 13-24 register).
  2. This is repeated until the slave indicates it is ready.
  3. The master sends the other command with no data. The command is queued in the receive FIFO for the slave to process.
