Description

Access: No wait states, except if a write access occurs while a write access to this register is ongoing. In this case, wait states are inserted in the second write access until the previous one is completed. The latency of the second write access can be up to 2 x PCLK1 + 6 x I2CCLK.

Fields

OA2

Interface address bits 7:1 of address Note: These bits can be written only when OA2EN=0.

OA2MSK

Own Address 2 masks Note: These bits can be written only when OA2EN=0. As soon as OA2MSK is not equal to 0, the reserved I2C addresses (0b0000xxx and 0b1111xxx) are not acknowledged even if the comparison matches.

OA2EN

Own Address 2 enable
