External Interrupt Module (IRQ1)
15.6 IRQ Module During Break Interrupts
15.7 IRQ Status and Control Register
Advance Information
204
Address:
The system integration module (SIM) controls whether the IRQ interrupt
latch can be cleared during the break state. The BCFE bit in the SIM
break flag control register (SBFCR) enables software to clear the latches
during the break state. (See
134
To allow software to clear the IRQ latch during a break interrupt, write a
logic 1 to the BCFE bit. If a latch is cleared during the break state, it
remains cleared when the MCU exits the break state.
To protect the latch during the break state, write a logic 0 to the BCFE
bit. With BCFE at logic 0 (its default state), writing to the ACK bit in the
IRQ status and control register during the break state has no effect on
the IRQ latch.
The IRQ status and control register (ISCR) controls and monitors
operation of the IRQ module. The ISCR has these functions:
