TDM interface specifications

4.5.3

Configuration 3



Delayed: SLOT0 data MSB is sampled on the second rising edge of BCLK after rising

edge of WCLK (delayed I²C register TDM_CTRL_REG (2Eh) bit 6 equal to one)



Data valid: data valid on the rising edge of BCLK (data_valid I²C register

TDM_CTRL_REG (2Eh) bit 5 equal to zero)

Figure 11. WCLK, SDOUT change on the falling edge of BCLK and are valid on the

rising edge of BCLK, delayed

Note:

Setup and hold times are defined in Table 6: TDM interface characteristics.
