Table4-16. TESCR2 Field Descriptions

Bits Name Description
0 Reserved, should be cleared.
1 REGS Internal registers error. An error occurred in a transaction to the PowerQUICCII’s internal registers.
2 DPR Dual port ram error. An error occurred in a transaction to the PowerQUICCII’s dual-port RAM.
3 Reserved, should be cleared.
4 Reserved, should be cleared.
PCI0 MPC8250, MPC8265, and MPC8266 only: PCI memory space 0 error. An error occurred in a
transaction to the PCI memory space configured by PCIBR0 and PCIMSK0.
5 Reserved, should be cleared.
PCI1 MPC8250, MPC8265, and MPC8266 only: PCI memory space 1 error. An error occurred in a
transaction to the PCI memory space configured by PCIBR1 and PCIMSK1.
6 Reserved, should be cleared.
7 LCL Local bus bridge error. An error occurred in a transaction to the PowerQUICCII’s 60x bus to local
bus bridge.
8–15 PB Parity error on byte. There are eight parity error status bits, one per 8-bit lane. A bit is set for the
byte that had a parity error.
16–27 BNK Memory controller bank. There are twelve error status bits, one per memory controller bank. A bit
is set for the 60x bus memory controller bank that had an error. Note that this field is invalid if the
error was not caused by ECC or parity checks.
28–31 Reserved, should be cleared.
