(1) See
Table 35
(2) Serial interrupt that occurs when BC[6:0] = 01. No serial interrupt if BC[6:0] > 01.
(3) Defined state when the number of bytes sent is equal to the value in I2CCOUNT register and an ACK has been received for
all the bytes sent.
(4) Defined state when a NACK received while number of bytes sent is lower than or equal to value in I2CCOUNT register.
(5) Master Receiver Byte mode is entered when MODE = 0. Master Receiver Buffered mode is entered when MODE = 1.
Remark:
The master should never transmit its own slave address.
