both the master device and slave device issue an interrupt (INTIICA: end of transfer).
The slave device reads the received data and releases the wait status (WREL = 1).
The start condition trigger is set again by the master device (STT = 1) and a start condition (SDA0 = 0 and
SCL0 = 1) is generated once the bus clock line goes high (SCL0 = 1) and the bus data line goes low (SDA0
= 0) after the restart condition setup time has elapsed. When the start condition is subsequently detected,
the master device is ready to communicate once the bus clock line goes low (SCL0 = 0) after the hold time
has elapsed.
