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
circuitry and cannot be permanently altered by the user. Program memory can be erased
without endangering 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.
There are 32 bytes of trim data. To modify one of these values the user code must first
write a value between
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
Trim Bit Address Register. The next read from the Trim Bit Data register returns the
working value of the target trim data byte.
The trim address ranges from information address 20-3F only. The remainder of the
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
factory programmed values intended for use in software correcting the device’s analog
performance. To read these values, the user code must employ the LDC instruction to
access the information area of the address space as defined in
page
The following code example shows how to read the calibration data from the Flash
Information Area.
; get value at info address 60 (FE60h)
ldx FPS, #%80 ; enable access to flash info page
