Signal Description

MODD

Input Input

Mode Select DÑMODD is an active-low

Schmitt-trigger input, internally synchronized to

CLKOUT. MODA, MODB, MODC, and MODD select

one of 16 initial chip operating modes, latched into the

OMR when the RESET signal is deasserted.

IRQD

Input

External Interrupt Request DÑAfter reset, this input

becomes a level-sensitive or negative-edge-triggered,

maskable interrupt request input during normal

instruction processing. If IRQD is asserted

synchronous to CLKOUT, multiple processors can be

resynchronized using the WAIT instruction and

asserting IRQD to exit the wait state. If the processor is

in the stop standby state and IRQD is asserted, the

processor will exit the stop state.

HI08

The HI08 provides a fast parallel-data-to-8-bit port that may be connected directly to the

host bus. The HI08 supports a variety of standard buses and can be directly connected to

a number of industry standard microcomputers, microprocessors, DSPs, and DMA

hardware.
