PLL_MODE. Set to 01
PLL_CFG. This PowerQUICC III device supports the following:
NEXEN, R1DPE, R2DPE, MPXTT, MSHARS, SSHAR, ATS, and MID are not implemented
On PowerQUICC III devices, ABE must be set to ensure that cache and TLB management instructions
operate properly on the L2 cache.
Please refer to the description of HID1[RFXE] in
Register 1 (HID1).”
If RFXE is 0, conditions that cause the assertion of core_fault_in cannot directly cause the e500 to generate
a machine check; however, PowerQUICC III devices must be configured to detect and enable such conditions.
The following describes how error bits should be configured:
Local bus controller parity errors. LTEDR[PARD] must be cleared and LTEIR[PARI] must be set to ensure that
an parity errors can generate an interrupt. See
(LTEDR),”
The PIR value is all zeros on PowerQUICC III devices.
The PVR reset value is 0x80 nn _ nnnn. See
PVR[VERSION] = 0x80 nn
PVR[REVISION] = 0x nnnn
The SVR reset value is 0x80 nn _ nnnn. See
The alternate time base defines a time base counter similar to the time base defined in architecture. It is
intended to be used for measuring time in implementation defined intervals. It differs from the defined Time
Base in that it is not writable and always counts up, wrapping when the 64-bit count overflows. It defines two
SPRs, ATBL (SPR 526) and ATBL (SPR 527).
• ECM mapping errors: EEER[LAEE] must be set. See
• L2 multiple-bit ECC errors: L2ERRDIS[MBECCDIS] must be cleared to ensure that error can be detected.
• DDR multiple-bit ECC errors. ERR_DISABLE[MBED] and ERR_INT_EN[MBEE] must be zero and
• PCI. The appropriate parity detect and master-abort bits in ERR_DR must be cleared and the
L2ERRINTEN[MBECCINTEN] must be set. See
DDR_SDRAM_CFG[ECC_EN] must be one to ensure that an interrupt is generated. See
“Register Descriptions.”
