Option Bit Types
This section describes the five types of Flash option bits.
User Option Bits
The user option bits are contained in the first two bytes of program memory. User access
to these bits has been provided because these locations contain application-specific device
configurations. The information contained here is lost when page 0 of the program mem-
ory is erased.
Trim Option Bits
The trim option bits are contained in the information page of the Flash memory. These bits
are factory programmed values required to optimize the operation of onboard analog cir-
cuitry and cannot be permanently altered. Program Memory may be erased without endan-
gering these values. It is possible to alter working values of these bits by accessing the
Trim Bit Address and Data registers, but these working values are lost after a power loss
or any other reset event.
There are 32 bytes of trim data. To modify one of these values the user code must first
write a value between
and
into the Trim Bit Address Register. The next write to
00H
1FH
the Trim Bit Data Register changes the working value of the target trim data byte.
Reading the trim data requires the user code to write a value between
and
into the
00H
1FH
Trim Bit Address Register. The next read from the Trim Bit Data Register returns the
working value of the target trim data byte.
Note:
The trim address range is from information address
only. The remainder of the
20–3F
information page is not accessible through the trim bit address and data registers.
Calibration Option Bits
The calibration option bits are also contained in the information page. These bits are fac-
tory-programmed values intended for use in software correcting the device’s analog per-
formance. To read these values, the user code must employ the LDC instruction to access
the information area of the address space as defined in See the
Flash Information Area
sec-
tion on page 17.
Serialization Bits
As an optional feature, Zilog is able to provide factory-programmed serialization. For seri-
alized products, the individual devices are programmed with unique serial numbers. These
serial numbers are binary values, four bytes in length. The numbers increase in size with
each device, but gaps in the serial sequence may exist.
