RBEN:

The receive bit error rates testing link enable bit (RBEN) controls the receive bit error rate

testing port. When RBEN is set high, RBSEL[2:0] is a binary number that selects a receive

link (RD[7:0]/RCLK[7:0]) to be the source of data for RBD and RBCLK outputs. When RBEN

is set low, RBD and RBCLK are held tri-stated.

TBSEL[2:0]:

The transmit bit error rates testing link select bits (TBSEL[2:0]) controls the over-writing of

transmit data on TD[7:0] by data on TBD when transmit bit error rate testing is enabled (TBEN

set high) and the selected link is not in line loopback (LLBEN[n] set low). TBSEL[2:0] is a

binary number that selects a transmit link (TD[7:0]/TCLK[7:0]) to carry the data on TBD. The

TBCLK output is a buffered version of the selected one of TCLK[7:0]. TBSEL[2:0] is ignored

when TBEN is set low.

TBEN:

The transmit bit error rates testing link enable bit (TBEN) controls the transmit bit error rate

testing port. When TBEN is set high and the associated link in not in line loopback (LLBEN

set low), TBSEL[2:0] is a binary number that selects a transmit link data output (TD[7:0]) to

carry the data on TBD and selects a transmit link clock (TCLK[7:0]) as the source of TBCLK.

When TBEN is set low, all transmit links are processed normally and TBCLK is held tri-stated.

Reserved[3:0]:

The reserved bits (Reserved[3:0]) must be set low for the correct operation of the FREEDM-8

device.
