7 5 3 Claim Information Requested Target Token Rotation Time (TREQ)
The Requested Target Token Rotation Time is stored in registers TREQ0 – TREQ3 TREQ(31 – 0) is represented as a negative
two’s complement number This value is transmitted in all Claim frames generated by the Ring Engine
Bits TREQ(31 –24) are always transmitted as and compared with FFh and bits TREQ(7 – 0) are always transmitted as and
compared with 00h independent of the value stored in the MAC Parameter RAM Bit TREQ(0) is transmitted last TREQ is
therefore programmable with 20 48 s resolution and a maximum value of 1 34 seconds
