3.8.9 Device error event register (DEE)
The bits of this register hold the errors that occurred during operation (operation
errors). So each bits of the DEC sets the according bit of the DEE.
The DEE can be read but not set. Reading clears the DEE.
3.8.10 Device error event enable register (EDE)
The bits of the EDE are used to select which bits of the DEE shall influence bit 3
(DES) of the STB. The 8 bits of the EDE are related by logical "AND" to the according
8 bits of the DEE. These 8 results are combined by logical "OR" so that any "hit"
leads to a logical 1 in bit 3 (DES) of the STB. As any bit of the STB can assert an
SRQ every error (bit of the DEE) can be used to assert an SRQ.
