2.2.3.1 Example 1 – Pulse Mode Indication on COL with Byte Mask (DP83822)

Byte Mask = 00-FF-FF-FF-FF-FF-FF-FF (Masking Bytes 8 to 63 of the 64-byte pattern)

Pattern = 01-23-45-67-89-AB-CD-EF (First eight Bytes programmed, Byte 8 to Byte 63 default to ‘0’ since they are don’t cares due to Byte Mask)

To enable Custom Pattern detection with pulse (8 clock cycles) indication on COL use the following register writes:
