Standard Event Register
The Standard Event Register set includes two 8-bit registers:
•
Standard Event Status Register:
Reports when a predefined event has occurred. The register
latches the event and the corresponding bit remains set until it is cleared by a read.
•
Standard Event Status Enable Register:
You can enable or disable bits in this register. This
allows the predefined event (from the Standard Event Status Register) to set the ESB of the
Status Byte Register.
