3.8 Status reporting
ITC500 / page 96
3.8.9 Device error event register (DEE)
The bits of this register hold the errors that occurred during operation (operation
errors). So each bit 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. This 8 results are connected 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.
