14.0 CN8236 Registers
14.4 Scheduler Registers
0xc0
The PCR_QUE_INT01 register fields are used to store the two lower PCR values used in PCR shaping on
priority queues that have been enabled for PCR shaping by setting the QPCR_ENAx bits in the SCH_PRI
register. QPCR_INTx values are used in order: 3, 2, 1, and 0; highest to lowest. PCR is determined by
1 / (QPCR_INTx
14.4.1 0xc4
The PCR_QUE_INT23 register fields are used to store the two highest PCR values used in PCR shaping on
priority queues that have been enabled for PCR shaping by setting the QPCR_ENAx bits in the SCH_PRI
register. QPCR_INTx values are used in order: 3, 2, 1, and 0; highest to lowest. PCR is determined by
1 / (QPCR_I24).

The assigned PCR interval, entered as number of schedule table slots,
used to map to the 3rd-highest priority queue that is enabled for PCR
shaping (using the QPCR_ENAx bits in the SCH_PRI register).
The assigned PCR interval, entered as number of schedule table slots,
used to map to the 4th-highest priority queue that is enabled for PCR
shaping (using the QPCR_ENAx bits in the SCH_PRI register).
The assigned PCR interval, entered as number of schedule table slots,
used to map to the highest priority queue that is enabled for PCR shaping
(using the QPCR_ENAx bits in the SCH_PRI register).
The assigned PCR interval, entered as number of schedule table slots,
used to map to the 2nd-highest priority queue that is enabled for PCR
shaping (using the QPCR_ENAx bits in the SCH_PRI register).
