The I2C_XSAR register is used in conjunction with the I2C_SAR register to provide
10-bit addressing of the I
8 bits of the 10-bit slave address. The full 10-bit address is supplied by {I2C_SAR[2:1],
I2C_XSAR[7:0]}.
When the register receives an address starting with
the I
after receiving the I2C_XSAR byte (the device does not generate an interrupt at this
point). After the next byte of the address (I2C_XSAR) is received, the I
interrupt and goes into SLAVE mode. Then I2C_SAR[2:1] are used as the upper 2 bits for
the 10-bit extended address. The full 10-bit address is supplied by {I2C_SAR[2:1],
I2C_XSAR[7:0]}. See
