753 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 2048 ms resolution and a maximum value of 134 seconds
