NOTE
The pulse width requirement for general-purpose input is applicable for the XBIO and
ADCSOC pins as well.
6.20 Serial Peripheral Interface (SPI) Master Mode Timing
Table 6-26 lists the master mode timing (clock phase = 0) and Table 6-27 lists the timing (clock
phase = 1). Figure 6-26 and Figure 6-27 show the timing waveforms.
