(Old) (2) RDRY = 1, RD2B = 0
... This clears the data inside the buffer and resets the RDRY flag. ...

... The receive data buffer ... and resetting the RD2B flag. ...
Even when the receive data buffer is full, ... and the new data will overwrite the shift register data.
(New) (2) RDRY = 1, RD2B = 0
... This resets the RDRY flag. ...
(3) RDRY = 1, RD2B = 1
... The receive data buffer outputs the oldest data first. This resets the RD2B flag. ...
Even when the receive data buffer is full, ... In this case, the last received data cannot be read.

I2CM: Data reception control
(Old) The data is loaded to the shift register in sequence at the clock rising edge, with the MSB leading.
RXE is reset to 0 when D6 is loaded.
(New) The data is shifted into the shift register from the MSB first in sync with the clock.
RXE is reset to 0 when D7 is loaded.

I2CM: End of data transfers (Generating stop condition)
(Old) The stop condition generation can be reserved. ... data transfer (including ACK transfer) ends.
(New) Before STP can be set to 1, confirm that TBUSY or RBUSY is reset to 0 from 1 (this indicates that ...
