I2C_EXTEND_EN

5:5

Enable PAGE decoding from the 3 LSBs of the incoming slave

address.

0: DA9155M responds normally to the I2C slave address

programmed in IF_BASE_ADDR. The register map page is

changed by writing to the PAGE register.

1: DA9155M will respond to multiple the slave addresses and

decode the PAGE from the 3 LSBs.

IF_BASE_ADDR[7:4] + 0: PAGE = 0x00

IF_BASE_ADDR[7:4] + 1: PAGE = 0x02

IF_BASE_ADDR[7:4] + 2: PAGE = 0x04

IF_BASE_ADDR[7:4] + 3: PAGE = 0x06.
