24.5.1
Whether a start or a stop condition has been detected is determined.
A start condition detect interrupt request is generated when the SDA2 pin changes state from high to low while
the SCL2 pin is in the high state. A stop condition detect interrupt request is generated when the SDA2 pin
changes state from low to high while the SCL2 pin is in the high state.
Because the start and stop condition detect interrupts share an interrupt control register and vector, check the
BBS bit in the U2SMR register to determine which interrupt source is requesting the interrupt.
Figure 24.15 shows the Detection of Start and Stop Conditions.
