Mode 1 is the middle frequency transfer mode. Maximum transfer frequency and transmission distance are mean
between mode 0 and mode 2. The SDTY/SDTZ data change after 50 ns (typical) from when the SCKA/SCKB
rising clock is input.
Mode 2 is the high-frequency transfer mode. Maximum transfer frequency is highest in the three timing modes.
This mode should be used for short distance data transmission. SDTY/SDTZ data change after 30 ns (typical)
from when the SCKA/SCKB rising clock is input. The timing diagram for each mode is shown in Figure 30 to
Figure 32.
