Pin Descriptions
Interrupts
Interrupts are controlled by register 6 (see Register Description). The INT pin (pin 2) goes high to signal an
interrupt. Interrupts are then cleared by reading any register. However, if the MK712 is in the process of generating
an interrupt during a read cycle, then the interrupt is not cleared and INT will stay high. This internal process may
take 100ns, and so to guarantee that the interrupt is cleared, two successive read cycles may be necessary.
