Section 17 I
17.3.7
SARA sets slave addresses. When the chip is in slave mode, if the upper 7 bits in SARA match the
upper 7 bits of the first frame received after a start condition, the chip operates as the slave device.
17.3.8
SARB sets slave addresses. When the chip is in slave mode, if the upper 7 bits in SARB match the
upper 7 bits of the first frame received after a start condition, the chip operates as the slave device.
