Note:
  • If one of the Logical layers supported by the RapidIO II IP core is not selected in the RapidIO II parameter editor, the corresponding bits in the Source Operations CARs are set to zero by default.
  • The reset value of the Source Operations CAR is the result of the bitwise exclusive-or operation applied to the default values and the value you specify for Source Operations CAR override in the RapidIO II parameter editor.
36 The default value is 1'b1 if you turn on Enable I/O Logical layer Slave module in the RapidIO II parameter editor. The default value is 1'b0 if you turn off Enable I/O Logical layer Slave module in the RapidIO II parameter editor.
37 The default value is 1'b1 if you turn on Enable Doorbell support in the RapidIO II parameter editor. The default value is 1'b0 if you turn off Enable Doorbell support in the RapidIO II parameter editor.
38 The default value is 1'b1 if you turn on Enable Maintenance module in the RapidIO II parameter editor. The default value is 1'b0 If you turn off Enable Maintenance module.
