Bits Name Function
[31] TYPE3

Selects the resource type for event 3:

0b0Single selected resource.
0b1Boolean combined resource pair.
[30:28] - Reserved. RAZ/WI.
[27:24] SEL3

Selects the resource number, based on the value of TYPE3:

When TYPE3 is 0b0, selects a single selected resource from 0-15 defined by bits[3:0].

When TYPE3 is 0b1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].

[23] TYPE2

Selects the resource type for event 2:

0b0Single selected resource.
0b1Boolean combined resource pair.
[22:20] - Reserved. RAZ/WI.
[19:16] SEL2

Selects the resource number, based on the value of TYPE2:

When TYPE2 is 0b0, selects a single selected resource from 0-15 defined by bits[3:0].

When TYPE2 is 0b1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].

[15] TYPE1

Selects the resource type for event 1:

0b0Single selected resource.
0b1Boolean combined resource pair.
[14:12] - Reserved. RAZ/WI.
[11:8] SEL1

Selects the resource number, based on the value of TYPE1:

When TYPE1 is 0b0, selects a single selected resource from 0-15 defined by bits[3:0].

When TYPE1 is 0b1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].

[7] TYPE0

Selects the resource type for event 0:

0b0Single selected resource.
0b1Boolean combined resource pair.
[6:4] - Reserved. RAZ/WI.
[3:0] SEL0

Selects the resource number, based on the value of TYPE0:

When TYPE0 is 0b0, selects a single selected resource from 0-15 defined by bits[3:0].

When TYPE0 is 0b1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].
