ASAHI KASEI
In case of serial mode, the DIF0-2 bits as shown in Table 4 support five serial formats. In case of parallel mode, two
formats (Mode 2 and 3) are supported by DIF pin (Table 5). In all modes the serial data is MSB-first, 2’s compliment
format. The SDTO is clocked out on the falling edge of BICK and the SDTI is latched on the rising edge.
