(b) If a start condition is issued while the device is receiving a write instruction (device address,

R/W, address, and data), this write instruction is discarded and the next instruction is accepted.

(A byte write is given below as an example. This is the same as a page write.)

(c) If a stop condition is issued while the device is receiving a write instruction (device address,

R/W, address, and data), the device enters the standby state. However, the device ignores the

stop condition while sending an acknowledge signal after it receives the D0 bit. (A write

operation starts.)
