The command and status formats for this mode can be seen in Figure 6.7 below with a description of
each field in Table 6.6:
Command:
Status:
Figure 6.7 SPI Command and Status Structure
Field
Description
A2:A0
Address of slave being used in a multi-slave environment. This would typically be used in the
scenario where a shared data bus is used.
R/W#
Set to 1 for a read and 0 for a write.
Z
Tri-stated.
TXE
Transmit Empty.
When 1 the Slave transmit buffer has no new data to transmit.
When 0 the Slave transmit buffer does have new data.
RXF
Receive Full.
When 1 the Slave receive buffer has new data which has not been read yet.
When 0 the Slave receive buffer is empty and can be safely written to.
ACK
Set to 1 when a Slave has correctly decoded its address.
