*1 : The interrupt request flag is cleared by the EI
2
OS interrupt clear signal.
*2 : The interrupt request flag is cleared by the EI
2
OS interrupt clear signal. A stop request is available.
Notes :
N/A : The interrupt request flag is not cleared by the EI
2
OS interrupt clear signal.
For a peripheral module with two interrupt causes for a single interrupt number, both interrupt request flags
are cleared by the EI
2
OS interrupt clear signal.
At the end of EI
2
OS, the EI
2
OS clear signal will be asserted for all the interrupt flags assigned to the same
interrupt number. If one interrupt flag starts the EI
2
OS and in the meantime another interrupt flag is set by
a hardware event, the later event is lost because the flag is cleared by the EI
2
OS clear signal caused by the
first event. So it is recommended not to use the EI
2
OS for this interrupt number.
If EI
2
OS is enabled, EI
2
OS is initiated when one of the two interrupt signals in the same interrupt control
register (ICR) is asserted. This means that different interrupt sources share the same EI
2
OS Descriptor
which should be unique for each interrupt source. For this reason, when one interrupt source uses the
EI
2
OS, the other interrupt should be disabled.
