13.2.2.6.4 Simple Commands
To send a command with no data to the slave, the master does the following:
- Sends a POLL command and verifies that the slave is ready (no RXBUSY from Table 13-24 register).
- This is repeated until the slave indicates it is ready.
- The master sends the other command with no data. The command is queued in the receive FIFO for the slave to process.
