What is the Chip Address for ADAU1761 in SPI mode?

Trying to understand the ADAU1761 SPI mode chip address.  In I2C mode, it looks like it is 0x38H.  Table 22 of the data sheet suggests that the chip address is 00 followed by R/W bit, with bit 0 going out the COUT pin first.  Table 23 shows Byte 0 as chip_address[6:0],R/W which almost suggests that bit 6 goes first with R/W following bit 0.


Can someone help clarify what the chip address should be and what the format is?  A figure for SPI transfer similar to Figure 49 would be most helpful.
