The I2Cx_SAR register, indicated in
SLAVE mode and allows 10-bit addressing in conjunction with the I2Cx_xSAR register.

interrupt at this point). After the next byte of the address (I2Cx_xSAR) is received, the I
generates an interrupt and enters SLAVE mode. Then I2Cx_SAR[2:1] is used as the upper
2 bits of the 10-bit extended address. The full 10-bit address is returned by
{I2Cx_SAR[2:1], I2Cx_xSAR[7:0]}.
The I2Cx_xSAR register, listed in
register to provide 10-bit addressing for the I
value forms the lower 8 bits of the 10-bit slave address. The full 10-bit address is returned
by {I2Cx_SAR[2:1], I2Cx_xSAR[7:0]}.
