13.0 RS8234 Registers
13.4 Scheduler Registers
0xc0 - PCR Queue Interval 0 and 1 Register (PCR_QUE_INT01)
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 x SYSCLK_period x SLOT_PER).
0xc4 - PCR Queue Interval 2 and 3 Register (PCR_QUE_INT23)
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_INTx x SYSCLK_period x SLOT_PER).

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).
