error event and reset by a microprocessor read operation.
Bits 15:10 Bits are reset upon reading of the interrupt generating register.
Parity error on UTOPIA bus
Parity error on external RAM
In order to prevent external RAM parity errors, the external RAM should
be written completely during board initialization by the microprocessor.
