RSPCK oscillation.
•
SSL negation delay
PDL_SPI_SSL_DELAY_MINIMUM or
PDL_SPI_SSL_DELAY_EXTENDED
Select the minimum or extended delay between
the end of RSPCK oscillation and the negation of
the active SSL pin.
•
Next-access delay
PDL_SPI_NEXT_DELAY_MINIMUM or
PDL_SPI_NEXT_DELAY_EXTENDED
Select the minimum or extended delay between

Remarks
•
For Slave mode operation, configure command 0.
•
When Clock-synchronous Slave mode is used, avoid selecting mode 0 or mode 2.
•
If parity is enabled while in Master mode, both the frame data length and data transfer format
should be the same for each command.
