Chapter 4

Programmer’s Model for Test

This chapter describes the registers of the ARM PrimeCell Static Memory Controller (PL092) and provides details required when programming the microcontroller. It contains the following:

•Scan testing on page 4-2.

Programmer’s Model for Test

4.1Scan testing

The PrimeCell SMC has been designed to simplify:

•the insertion of scan test cells

•the use of Automatic Test Pattern Generation (ATPG).

This is the recommended method of manufacturing test.
