I2CS: Bus free request with an input from the #BFR pin
(Old) When this function is enabled, a Low pulse (five peripheral module clock (PCLK) cycles or more
pulse width is required) input to the #BFR pin sets BFREQ/I2CS_STAT register to 1.
(New) When this function is enabled, a low pulse (One peripheral module clock (PCLK) cycles or more
pulse width is required. Two PCLK clock cycles or more pulse width is recommended.) input to the
#BFR pin sets BFREQ/I2CS_STAT register to 1.

I2CS: Starting data transfer
(Old) Both BUSY and SELECTED are maintained at 1 until a stop condition is detected.
(New) BUSY is maintained at 1 until a stop condition is detected. SELECTED is maintained at 1 until a
