PCMD3140-Q1: 6 MHz PDMCLK with four PDM Mics?

Part Number: PCMD3140-Q1
Other Parts Discussed in Thread: PCMD3140

The PCMD3140-Q1 datasheet (www.ti.com/.../SBASAH3) lists a maximum PDMCLK frequency of 6.144 MHz, but Table 7-60 indicates that the 6 MHz configuration is "applicable only for PDM channel 1 and 2."

Is there any way to configure this chip to convert data from four PDM mics with a PDMCLK frequency of 6 MHz?
