General Description

General Release Specification

MC68HC05RC17 — Rev. 2.0

General Description

STOPEN — STOP Instruction Enable

When the STOP option is selected (STOPEN = 1), the STOP

instruction is enabled.

When the STOP option is deselected (STOPEN = 0), the STOP

instruction is equivalent to a WAIT instruction.

IRQ — IRQ sensitivity

When the IRQ option is selected (IRQ = 1), edge- and level-sensitive

IRQ is enabled.

When the IRQ option is deselected (IRQ = 0), edge-only sensitive IRQ

is enabled.

NOTE:

The port B keyscan interrupt sensitivity will match that of the IRQ

sensitivity. (See 4.7 External Interrupt (IRQ/Port B Keyscan) for more

information.)

1.5 Signal Description

Pinout for the 28-pin small outline integrated circuit (SOIC) package is

shown in Figure 1-2. Pinout for the 28-pin plastic dual in-line (PDIP)

package is shown in Figure 1-3. The signals are described in the

following subsections.

NOTE:

Consult the factory for availability of 28-pin dual in-line and higher pin

count packages.

1.5.1 VDD and VSS

Power is supplied to the microcontroller’s digital circuits using these two

pins. VDD is the positive supply and VSS is ground.
