(0x0000001c/0xffff001c) without requiring a branch. Because of this bug, the first instruction of
such an FIQ handler may be executed twice when it is not a branch instruction.
When a ‘NOP’ is placed at the beginning of the FIQ handler, the ‘NOP’ executes twice and no
incorrect behavior results. When a branch instruction is placed at the beginning of the handler, it
does not execute twice.
