INSBI
INSBI, EXSBI:
The INSBI and EXSBI register bits allow software to determine whether the INSBI and/or
EXSBI blocks are producing an interrupt on the INTB output pin. A logic 1 indicates an
interrupt is being produced from the corresponding block.
Reading this register does not remove the interrupt indication; the corresponding block’s
interrupt status register must be read to remove the interrupt indication.
