Exception code

An exception occurred during read: H'040

An exception occurred during write: H'060

•

Remarks

The logical address (32 bits) that caused the exception is set in TEA and the MMU registers
are updated. The vector address of the TLB miss exception is VBR + H'0400. To speed up
TLB miss processing, the offset differs from other exceptions.

TLB Invalid Exception:

•

Conditions

Comparison of TLB addresses shows address match but V = 0.
