® Intel 80219 General Purpose PCI Processor Core Errata 6. Incorrect Decode of Unindexed Mode, Using Addressing Mode 5, Can Corrupt Protected Registers Problem: The instruction decoder incorrectly decodes the valid combination of P=0, U=1 and W=0, when using unindexed mode in addressing mode 5 (load and store coprocessor). In this case, the LDC or STC should produce consecutive address loads or stores, with no base update until the coprocessor signals that it has received enough data. Instea

® Intel 80219 General Purpose PCI Processor Core Errata 10. Aborted Store that Hits the Data Cache May Mark Writeback Data As Dirty Problem: When there is an aborted store that hits clean data in the data cache (data in an aligned four word range, that has not been modified from the core, since it was last loaded in from memory or cleaned), the data in the array is not modified (the store is blocked), but the dirty bit is set. When the line is then aged out of the data cache or explicitly clea

Performance Monitor Unit Event 0x1 Can Be Incremented Erroneously by Unrelated Events Problem: Event 0x1 in the performance monitor unit (PMU) can be used to count cycles in which the instruction cache cannot deliver an instruction. The only cycles counted should be those due to an instruction cache miss or an instruction TLB miss. The following unrelated events in the core, also causes the corresponding count to increment when even

Updating the JTAG parallel register requires an extra TCK rising edge Problem: IEEE 1149.1 states that the effects of updating all parallel JTAG registers should be seen on the ® falling edge of TCK in the Update-DR state. The Intel Xscale core parallel JTAG registers incorrectly require an extra TCK rising edge to make the update visible. Therefore, operations like hold-reset, JTAG break, and vector traps require either an extra TCK

The ATU Returns Invalid Data for the DWORD that Target Aborted from the MCU when Using 32-Bit Memory, ECC Enabled and in PCI Mode The external PCI bus requests a read through the ATU to the MCU, starting at the high DWORD. Remember the MCU is in 32-bit mode. The ATU requests multiple DWORDs since it pre-fetches, but starts at the high DWORD address. The MCU issues two DWORDs. First the high, followed by the low an

Boundary Scan Is Not Fully Compliant to the IEEE 1149.1 Specification Problem: The IEEE Standard 1149.1 specifies the boundary scan logic to support two main goals: 1. To allow the interconnections between the various components to be tested, test data can be shifted into all the boundary-scan register cells associated with component output pins and loaded in parallel through the component interconnections, into those cells

Undefined Data Processing-‘like’ Instructions are Interpreted as an MSR Instruction Problem: The instruction decode allows undefined opcodes, which look similar to the MSR (Move to Status register from an ARM register) instruction, to be interpreted as an MSR instruction. The mis-decoded MSR instruction also adds a SUBNV PC,0x4 to the instruction flow. Workaround: Do not use undefined opcodes of this form: 3130292827262524232221201918
