6.12.2 Interrupt Enable Flag
When the interrupt is enabled by the event, the program counter will jump to the interrupt address and
the enable interrupt flag (ENINT) bit0 is cleared, at the same time, all the interrupt will be disabled.
The only way to enable the interrupt again is to set the ENINT bit0 or execute the RTNI instruction.

When the interrupt is enabled by the event, the individual interrupt request signal is cleared by the
hardware automatically, but the other interrupt request signals will remain the same condition. The
only method of resetting the interrupt request signal is to execute the instruction CLR EVF, #I (I is a
8bits data, for example, CLR EVF, #00000001b instruction implies to clear TM0 interrupt request
signal), it is a 2 words / 2 cycles instruction; the format of the immediate data is shown below.
