SPI outputs valid—master mode (internal clock) delay
SPI outputs hold—master mode (internal clock) delay
SPI outputs valid—slave mode (external clock) delay
SPI outputs hold—slave mode (external clock) delay
SPI inputs—master mode (internal clock) input setup time
SPI inputs—master mode (internal clock) input hold time
SPI inputs—slave mode (external clock) input setup time
SPI inputs—slave mode (external clock) input hold time
