3.1.95 testRamBitToggle

Name

testRamBitToggle—assures that each memory location in the memory test block is written

with the test data pattern. Each memory location in the memory block is then written with the

test data pattern complemented. The memory under test is read back to verify that the

complement test data is properly retained. Each memory location in the memory block is then

written with the test data pattern. The memory under test is read back to verify that the test

data is properly retained. The test proceeds as follows: (1) Random data seed is copied into a

work register. (2) Work register data is shifted right one bit position. (3) Random data seed is

added to work register using unsigned arithmetic. (4) Data in the work register may or may not

be complemented. (5) Data in the work register is written to current memory location.

Note: testRamBitToggle only tests memory in blocks, thus specifying a memory area size that

is not a multiple of the block size results in part of the memory area being untested.

Synopsis

testRamBitToggle [-a] [-b] [-i] [-n] [-t] [-v]

Parameters

-a Ph: Address to Start (Default = Dynamic Allocation)

-b Ph: Block Size (Default = 16 KB)

-i Pd: Iterations (Default = 1)

-n Ph: Number of Bytes (Default = 1 MB)

-t Pd: Time Delay Between Blocks in OS Ticks (Default = 1)

-v 0: Verbose Output

Example

The following example indicates a typical display when using the testRamBitToggle

command.

MOTLoad> testRamBitToggle -v

Executing RAM Addressing: PASSED
