15.1.3.3 Arbitration
Unmatching of the transmit data and SDAi pin input data is checked synchronously with the rising edge
of SCLi. Use the ABC bit in the UiSMR register to select the timing at which the ABT bit in the UiRB
register is updated. If the ABC bit = 0 (updated per bit), the ABT bit is set to 1 at the same time
unmatching is detected during check, and is set to 0 when not detected. In cases when the ABC bit is set
to 1, if unmatching is detected even once during check, the ABT bit is set to 1 (unmatching detected) at
the falling edge of the clock pulse of 9th bit. If the ABT bit needs to be updated per byte, set the ABT bit
to 0 (undetected) after detecting acknowledge in the first byte, before transferring the next byte.
Setting the ALS bit in the UiSMR2 register to 1 (SDA output stop enabled) causes arbitration-lost to
occur, in which case the SDAi pin is placed in the high-impedance state at the same time the ABT bit is
set to 1 (unmatching detected).
