Interrupt Status (address 20h) (Read Only)
For all bits in this register, a “1” means the associated interrupt condition has occurred at least once since the reg-
ister was last read. A ”0” means the associated interrupt condition has NOT occurred since the last reading of the
register. Reading the register resets all bits to 0. Status bits that are masked off in the associated mask register will
always be “0” in this register.
