Chapter 4 – SocketModem Parallel Interface – A Programmer's Description Register Signal Definitions IER – Interrupt Enable Register (Addr = 1, DLAB = 0) The IER enables five types of interrupts that can separately assert the HINT output signal (Table 4– 2.). A selected interrupt can be enabled by setting the corresponding enable bit to a 1, or disabled by setting the corresponding enable bit to a 0. Disabling an interrupt in the IER prohibits setting the corresponding indication in the IIR and a
