transfer terminates after losing arbitration. When an INTSBI interrupt request
occurs the <PIN> is cleared to 0 and the SCL pin is pulled down to the low-level.
Either reading/writing from/to the SBI0DBR or setting the <PIN> to 1 will release
the SCL pin after taking t

The TMP91C820A loses arbitration when
transmitting a slave address and receives
a slave address for which the value of the
direction bit sent from another master is 1.
In salve receiver mode the TMP91C820A
receives a slave address for which the
value of the direction bit sent from the
master is 1.
In salve transmitter mode a single word of
