Interrupt enable register B is used by the external processor to mask unnecessary interrupt sources for

interrupt B. Bits loaded with a 1 allow the corresponding interrupt condition to generate an interrupt on the

external pin. Conversely, bits loaded with zeros mask the corresponding interrupt condition from

generating an interrupt on the external pin. This register only affects the external pin, it does not affect the

bits in the interrupt status register. A given condition can set the appropriate bit in the status register and

not cause an interrupt on the external pin. To determine if this device is driving the interrupt pin either

AND interrupt status register B with interrupt enable register B or check the state of interrupt B in the

interrupt B active register.
