Transmitter Input Equalization Control Code Description
Control registers 228 through 233 permit input equalization control. Four bit code blocks (either bits 7 through 4 or 3
through 0 where bit 7 or 3 is the msb) are assigned to each channel.
Codes 1xxx are reserved.
Code 0111 calls for full scale equalization and code 0000 calls for no equalization.
Intermediate code values provide intermediate levels of compensation.
