Data Sheet
9.0 Built-in Test Functions
The AMIS-53000 has a number of test registers. These registers are not available to the general user of the AMIS-53000. However,
many of these registers control test features that are useful in the development of applications using the AMIS-53000.
Setup registers descriptions:
Test Unlock- A special code is required to unlock the functions of the test registers.
Test- Registers that route signals to pins for monitoring or turn internal circuits off for test.
9.1 TM Unlock Register
The developer designing the AMIS-53000 may desire to use some of the test modes to monitor the operation of the AMIS-53000 or to
determine the activity of some parameter. These registers are locked from use by a code word. To unlock the test registers contact
AMIS wireless product support to obtain the code. Enter this code in the unlock register to access the test registers. This register will
be reset with a reset of the part and thus will lock the user out of the test registers.
Setup registers descriptions:
Test Unlock- Register contains a code about the state the AMIS-53000 is operating in.
** Registers with the ** mark can be trimmed if the test registers are unlocked.

9.2 Test Registers
The following registers allow for signals to be routed to pins for monitoring. They also turn functions in the AMIS-53000 on and off for
measuring the operational parameters of the AMIS-53000.
9.2.1. IF Amp Manual Trim A
This register is used for factory testing of the AMIS-53000 and has no user functions.
9.2.2. IF Amp Manual Trim B
This register is used for factory testing of the AMIS-53000 and has no user functions.
9.2.3. PLL Manual Trim
This register is used for factory testing of the AMIS-53000 and has no user functions.
