Description

I2C own address 1 register

Fields

OA1

Interface own slave address 7-bit addressing mode: OA1[7:1] contains the 7-bit own slave address. Bits OA1[9], OA1[8] and OA1[0] are don’t care. 10-bit addressing mode: OA1[9:0] contains the 10-bit own slave address. Note: These bits can be written only when OA1EN = 0.
OA1MODE

Own address 1 10-bit mode Note: This bit can be written only when OA1EN = 0.

0 (B_0x0): Own address 1 is a 7-bit address.

1 (B_0x1): Own address 1 is a 10-bit address.
OA1EN

Own address 1 enable
