DA9213, DA9214, and DA9215's 4-WIRE interface offers two further configuration bits. Clock polarity

(CPOL) and clock phase (CPHA) define when the interface will latch the serial data bits. CPOL

determines whether SK idles high (CPOL = 1) or low (CPOL = 0). CPHA determines on which SK

edge data is shifted in and out. With CPOL = 0 and CPHA = 0, DA9213, DA9214, and DA9215 latch

data on the SK rising edge. If the CPHA is set to 1 the data is latched on the SK falling edge. CPOL

and CPHA states allow four different combinations of clock polarity and phase. Each setting is

incompatible with the other three. The host and DA9213, DA9214, and DA9215 must be set to the

same CPOL and CPHA states to communicate with each other.
