VMEbus Interrupter Vector Register

This register controls the VMEbus interrupter vector.

MPU Status and DMA Interrupt Count Register

This is the MPU status register and DMAC interrupt counter.

MLOB

When this bit is set, the MPU received a TEA and the
status indicated off-board. This bit is cleared by writing a
1 to the MCLR bit in this register.

MLPE

When this bit is set, the MPU received a TEA and the
status indicated a parity error during a DRAM data
transfer. This bit is cleared by writing a 1 to the MCLR bit
in this register.

MLBE

When this bit is set, the MPU received a TEA and no
additional status was provided. This bit is cleared by
writing a 1 to the MCLR bit in this register.

MCLR

Writing a 1 to this bit clears the MPU status bits 7, 8, 9,
and 10 (MLTO, MLOB, MLPE, and MLBE) in this
register.
