General Description

1.4 Mask Options

There is one user selectable option on the MC68HC705MC4; the COP

timer. This option is provided through a bit within a mask option register

(MOR) in the EPROM device, which is located and programmed at

$0F00. This option will be hard wired in the ROM-based device.

The ROM-based device (MC68HC05MC4) will offer these hard-wired

options.

•

COP Watchdog Timer Enabled with Option to Disable

•

Stop Instruction Enabled with Option to Disable

These options are compatible with the typical application environment in

which the device is expected to be used and will consequently allow the

OTP devices to be used in production.

1.5 Functional Pin Description

The following paragraphs describe the functionality of each pin on the

MC68HC705MC4 package (see Figure 1-2 and Figure 1-3). Pins

connected to subsystems which are described in other sections of this

document provide a reference to the section instead of a detailed

functional description.
