Note
The mode 0 master receive data consists of up to 19 bytes. There-
fore, the receive buffer (20 bytes) does not become full, and a return
code is not generated.

Slave reception
The order of generation of slave reception return codes is as shown in Figure 6-4.
Figure 6-4. Return Code Generation Order in Slave Reception
The minimum generation intervals for return codes in master transmission are shown below.
