Transmission starts with rising edge
Transmission starts with falling edge
Data is sampled with falling edge of PCLK
Data is sampled with rising edge of PCLK
Bit 0 is driven the whole PCLK-period
Bit 0 is driven during the first half of the
PCLK-period only
No shift takes place
Access to DXA/B and DRA/B is shifted for one
PCLK-per.
No offset is added
One data clock period is added
Seven data clock periods are added
