4.2.4
Control Register
The Control register provides output interfacing to the application software. Assertion of the ap-
propriate bits by the application software will cause the BPCC to generate outputs accordingly.
During startup, the state of Bit 0 is controlled by the NetBootLoader software. After the startup
is completed, the NetBootLoader sets Bit 0 to 1.
4.2.5
Event Register
The Event register provides status information about the Watchdog timer and various monitor
and control inputs. Depending on the type of event which occurs, interrupts may be generated
automatically which then require servicing. The application software is responsible for servicing
the interrupts as well as the other events, and, where applicable, the resetting of the event bits.
