Intel Stratix 10 User Manual

Description
Sets whether the PMA transmitter path, receiver path, or both are calibrated the next
time the PMA is enabled when using PMA attribute code 0x0001.
• 0x84[0]: 1'b1 to recalibrate the PMA transmitter path the next time the
transmitter is enabled
• 0x84[1]: 1'b1 to recalibrate the PMA receiver path the next time the receiver is
enabled
• 0x84[7:2]: 6'h00
• 8x85[7:0]: 8'h00
PMA Can Be Running While Updating PMA Attribute?
Yes
Return Value {0x89[7:0],0x88[7:0]}
0x0011
9.2.9. 0x0013: TX/RX Polarity and Gray Code Encoding
Attribute Code
0x0013
Description
Changes the state of TX polarity, RX polarity, or both.
• 0x84[0]: 1'b1 to invert TX polarity
• 0x84[1]: 1'b1 to enable TX Gray code in PAM4 mode
• 0x84[2]: 1'b1 to enable TX Precode (1/1+D) in PAM4 mode
• 0x84[3]: 1'b0 for even bits to be mapped to PAM4 LSB
• 0x84[3]: 1'b1 for even bits to be mapped to PAM4 MSB
• 0x84[4]: 1'b1 to invert RX polarity
• 0x84[5]: 1'b1 to enable RX Gray code in PAM4 mode
• 0x84[6]: 1'b1 to enable RX Precode (1/1+D) in PAM4 mode
• 0x84[7]: 1'b0 for RX even bits to be mapped to PAM4 LSB
• 0x84[7]: 1'b1 for RX even bits to be mapped to PAM4 MSB
• 0x85[0]: 1'b1 to set TX polarity to provided value in 0x84[0]
• 0x85[1]: 1'b1 to set RX polarity to provided value in 0x84[4]
• 0x85[2]: 1'b1 to set TX PMA4 MSB/LSB mapping, gray code encoding, precoding
to provided values on 0x84[3:1]
• 0x85[3]: 1'b1 to set RX PMA4 MSB/LSB mapping, gray code encoding, precoding
to provided values on 0x84[7:4]
• 0x85[7:4]: 4'h0
