2.1. Timing

A 46-bit instruction, loaded serially at the start of each test, controls the operation of the ARM L210 MBIST Controller. Chapter 3 MBIST Instruction Register describes how to write the instruction.

The timing diagrams in this section show the clock running at two different speeds:

If you do not have an on-chip PLL, both clocks relate to the clock driven by your ATE.

Timing diagrams in the following sections show the procedures for operating the ARM L210 MBIST Controller:
