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
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.
