MPU Local Bus Time-out

1-42
Status:
Bit 8 of the MPU Status and DMA Interrupt Count Register.
Address $FFF40048.
Comments:
This can be caused by a VMEbus time-out, a VMEbus BERR, or an
MVME162FX VMEbus access time-out. The latter is the time from
when the VMEbus has been requested to when it is granted.

An error occurred while the MPU was attempting an access.
MPU Notification:
TEA is asserted during an MPU access.
Status:
Bit 10 of the MPU Status and DMA Interrupt Count Register at
address $FFF40048 in the VMEchip2.
Comments:
No status was given as to the cause of the TEA assertion.
Description:
An error occurred while the MPU was attempting to access a local
resource.
MPU Notification:
TEA is asserted during the MPU access.
Status:
Bit 7 of the MPU Status and DMA Interrupt Count Register,
(actually in the DMAC Status Register) at address $FFF40048.

The local bus timer timed out. This usually indicates the MPU tried
to read or write an address at which there was no resource.
Otherwise, it indicates a hardware problem.
