I2C configuration 7.2.2
When using I2C mode, ensure jumpers J23 and J24 are fitted on the EVB. On the digital IO board
ensure jumpers J14, 17-18 and 19-20 fitted and jumpers J14, 7-8, 9-10 and 11-12 are removed when
in I2C mode is required. See
Table 2 for I2C jumper configuration selection.
The codec slave address for DA7322 is 0x34 and this is the 8bit value (34h for Write, 35h for Read).
SPI configuration 7.2.3
When using SPI mode, ensure jumpers J23 and J24 are removed on the EVB. On the digital IO
board, ensure jumper links on J14, 17-18 and 19-20 are removed and jumpers J14, 7-8, 9-10 and 11-
12 are fitted when SPI mode is required. See
Table 2 for SPI jumper configuration selection.
When reading/writing to registers in SPI mode, ensure the correct page mode is selected for the
paging area selected (register base address 0x00, 0x80 – see DA7322 data sheet).
