QSIU1
Incorrect clock Synchronization in 1:4 and 1:6 Modes
Date Added:
5/30/2000:
Description:
In PLL enabled mode, the core clock is not synchronized correctly with the bus
clock for even clock ratios, such as 1:4 and 1:6 (bus clock: core clock).
Do not use even bus clock to core clock ratios.
System Number:
5744
Fix Plan:
Rev 0.1
0K40A
QSIU3
TEA May Hang PPC Bus
Date Added:
5/30/2000:
Description:
TEA may hang the PPC bus if it is asserted between specific address and data phas-
es during a split transaction.
Workaround:
Enable Bus Monitor.
System Number:
5724
Fix Plan:
TBD
0K40A
QSIU4
Extended Mode on the Local Bus
Date Added:
6/13/2000:
Description:
Using Extended mode on the local bus can generate incorrect transactions in certain
combinations of consecutive reads and writes.
Workaround:
Do not use Extended mode on the local bus.
System Number:
5959
Fix Plan:
Not currently scheduled

QSIU5
Incorrect Data on PowerPC Bus
Date Added:
6/13/2000, modified 10/15/2002
Description:
The following sequence on the PowerPC bus can result in incorrect data:
1.
Read transaction with DACK before AACK.
2.
Failed atomic write transaction
3.
Write transaction
Workaround:
None
System Number:
5823

QSIU6
EE[4–5] Pins are Sampled on HRESET,SRESET and PORESET
Date Added:
8/31/2000
Description:
The EE[4–5] pins should be sampled only on PORESET, but they are sampled on
SRESET and HRESET as well. Changing the value of the EE[4–5] pins after PORESET negation
might prevent the chip from booting, because their value might choose a different or undefined
boot configuration.
Workaround:
The EE[4–5] values should be kept constant and equal to the values on PORE-
SET.
Fix Plan:
Rev A
0K40A
QSIU7
Pin IRQ7_INTOUT Not Open Drain
Date Added:
9/6/2000
Description:
INOUT pin IRQ7_INTOUT should be open-drain but not implemented as one.
Workaround:
Buffer INTOUT on the board when it is wire ORed.
Fix Plan:
