Slave Mode Slave Address

In Slave Mode Operation, (I2Cn_CTRL0.mstr = 0), set this field to the slave address

for the I2Cn port. For 7-bit addressing, the address occupies the least significant 7

bits. For 10-bit addressing, the 9-bits of address occupies the most significant 9 bit

and the R/W bit occupies the least significant bit.

Note: I2Cn_SLV_ADDR.ea controls if this field is a 7-bit or 10-bit address.
