10.6.86 QOSC7A - TOKEN_LIMIT_G3
Serial Interface Address:h591
Bits [7:0]
•
•
Bytes allow to to continue transmit out when regulated by Shaper logic.
(16byte/unit) (Default: 8’hC0)
QOSC79 and QOSC7A correspond to parameters from section 7.6 on the shaper for EF traffic. QOSC79 is an
integer less than 64, with granularity 1. QOSC7A is the programmed maximum value of the counter (maximum burst
size). This value is expressed in multiples of 16. QOSC79 and QOSC7A apply to Gigabit port 3. Register
QOSC51-CREDIT_C6_G3 programs the peak rate. See QoS application note for more information.
