Defined
[1:0] RO Reserved for this implementation 2'b00
Notes to Table 6–28:
(1) 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.
(2) 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.
(3) 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.
(4) Thedefault 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.
(5) 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.
