(2) Slave Mode (SBI0CR2.MST = 0)
Example: When the received slave address matches the SBI’s own address and the data direction
generates the INTS2 interrupt on four occasions: 1) when the SBI has received any slave address;
2) when the SBI has received a general-call address; 3) when the received slave address matches its
own address in the I2C0AR; and 4) when a data transfer has been completed in response to a
general-call.
