11.8.1 Additional Function for Table Read
The Table Read supervisory operation will return the Ver-
sion ID in the Accumulator. The value in the Accumulator
is divided into a high and low nibble, indicating major and
minor revisions, respectively. Note : The value in the X

The user has the option to define the access to the Flash
memory. A flexible system allows the user to select one
of four protection modes for each 64-byte block within
the Flash, based on the particular application. The pro-
tection mechanism is implemented by a device program-
mer using the System Supervisor Call. When this
command is executed, two bits within the data pro-
grammed into the Flash will select the protection mode.
It is not intended that the protection byte will be modified
by the user’s code. The following table lists the available
protection options:
