13.2.2.6.5 Data Receive Operation

To send data to the slave, the master does the following:

1. Sends a POLL command and verifies that the slave is ready and can accept the data.
2. This is repeated until the slave indicates that it is ready and can accept the data (no RXBUSY from Table 13-24 register).
3. The master sends the write command and data bytes. On receiving, the slave stores the command and data bytes in the receive FIFO. After CMDSIZE bits have been received, the CMD interrupt is generated.
4. The hardware automatically sets RxBUSY, if there are less than Table 13-22 storage locations left in the receive FIFO after the sequence completes.
