37.4.2.8 Host Operation in 10-Bit Addressing Modes
In Host 10-bit Addressing modes, the client’s 10-bit address and R/W bit
value are loaded into either the I2CxADB0 and I2CxADB1
registers (when ABD = 0
) or I2CxTXB (when ABD =
1
). When the host intends to read data from the client, it must
first transmit the full 10-bit address with the R/W bit clear
(R/W = 0
), issue a Restart condition, then
transmit the address high byte with the R/W bit set
(R/W = 1
). When the host intends to write
data to the client, it must transmit the full 10-bit address with the
R/W bit clear (R/W =
0
).
