Description
Set to override the TS1 number to be sen out in polling active state
with the value in bit (27:16) of this register from the specification
defined value.
Set to override the min time for a transmitter to stay with the value in
bit (15:8) of this register from the specification defined value.
Set to override the Max time for electrical idle transition with the value
in bit (7:0) of this register from the specification defined value.
–
TS1 number needed to be sent in Polling active state.
Minimum time (in symbol time) a transmitter must be in electrical idle. 0x5
Maximum time (in symbol time) to transition to a valid electrical idle
after sending an electrical idle ordered-set.
