2.2 Data Input Formats
Table 2.2 and Figure 2.1 show the data input formats. Microcontroller interface bits IBIT1, IBIT2,
and IBIT3 select the format.
In master mode, the BCKI clock rate varies through the range shown in 2.2.
In slave mode, the BCKI input clock is directly output through the IC internal buffer as the data
output bit clock (BCKO). Therefore, when using the digital data output, input the clock shown in
Table 2.2.
The IIS-compatible format can accept up to 24 bits of data. When inputting data shorter than 24
bits, fix the lower bits to 0.
