2.7 Host Interface (HI08)
The HI08 provides a fast, parallel data-to-8-bit port that can directly connect to the host bus. The
HI08 supports a variety of standard buses and can directly connect to a number of
industry-standard microcomputers, microprocessors, DSPs, and DMA hardware.

State
Mode Select C/External Interrupt Request C
Selects the initial chip operating mode during hardware reset and becomes a
level-sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. MODA, MODB, MODC, and MODD select one of
sixteen initial chip operating modes, latched into OMR when the RESET signal is
deasserted.
Internally synchronized to CLKOUT. If IRQC is asserted synchronous to CLKOUT,
multiple processors can be re-synchronized using the WAIT instruction and asserting
IRQC to exit the Wait state.
MODC/IRQC can tolerate 5 V.
Mode Select D/External Interrupt Request D
Selects the initial chip operating mode during hardware reset and becomes a
level-sensitive or negative-edge-triggered, maskable interrupt request input during
normal instruction processing. MODA, MODB, MODC, and MODD select one of
sixteen initial chip operating modes, latched into OMR when the RESET signal is
deasserted.
Internally synchronized to CLKOUT. If IRQD is asserted synchronous to CLKOUT,
multiple processors can be re-synchronized using the WAIT instruction and asserting
IRQD to exit the Wait state.
MODD/IRQD can tolerate 5 V.
