3.11 Serial Peripheral Interface Electrical
Specifications
3.11.1 Master Mode
Figure 11 and Figure 12 illustrate master mode timing. Timing values are shown in Table 33.
Table 33. SPI Master Mode Timing Characteristics

The numbers 7, 8 in the column labeled “Num” are missing. This has been done on purpose to be consistent
between the Master and the Slave timing shown in Table 34.
Conditions are shown in Table 6 unless otherwise noted, C
