Specifications

• Data Read—Reads transactions similar to the Address Read test, but focuses on the data bits. Patterns are placed on the data bus
to test for stuck data bits.
• Data Write—Places data patterns on the bus for testing the bus and looks for stuck data bits.
• Data Walking 1—Walks a 1 through the data bits within an address location and veries that the values are valid before
overwriting.
• Data Walking 0—Walks a 0 through the data bits and veries the value as it is testing.
• Data Sliding 1—Slides a 1 through the data testing for stuck bits. By xor of each shift to the data, when complete, the cell holds
all the 1s.
• Data Sliding 0—Slides a 0 through the data bits set to 1. By xor of each shift of the data, when complete, the cell holds all the
1s.
• Data Pattern—Writes four dierent patterns to memory locations within the specied region. The patterns are 0xFFFF, 0xFF00,
0xF0F0, 0xAAAA, 0xAA55 and 0x5555. The patterns are written as repeated portions of these patterns in the memory to ll the
memory and as Hamming patterns (such as Hamming [8,4], Hamming[16,11], Hamming[32,26] or Hamming[64,57]) encoding with the
additional most signicant byte (MSB) parity bit to cover the parity bits in the Hamming code. This pattern allows for detecting multiple
bit errors.
• Data Cache—Performs a rotation of a 16MB array in four clockwise rotations for 16 iterations of the complete rotation. The 16MB
size ensures that memory is not within the cache lines and causes cache ejections through each of the rotations.
