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 t
he
St
atus Byte Register.
