3.4.20. Sequencer State Transition Control Registers 0-2

The TRCSEQEVRn characteristics are:

Purpose

Defines the sequencer transitions that progress to the next state or backwards to the previous state. The ETM-R7 implements a sequencer state machine with up to four states.

Usage constraints

Can only be written when the ETM-R7 is disabled.

Configurations

Available in all configurations.

Attributes

See the register summary in Table 3.1 and Table 3.4.

Figure 3.21 shows the TRCSEQEVRn bit assignments.

BitsNameFunction
[31:16]-RAZ/WI
[15]B TYPE

Selects the resource type to move backwards to this state from the next state:

0

Single selected resource.

1

Boolean combined resource pair.

[14:12]-RAZ/WI
[11:8]B SEL

Selects the resource number, based on the value of B TYPE:

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

When B TYPE is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].

[7]F TYPE

Selects the resource type to move forwards from this state to the next state:

0

Single selected resource.

1

Boolean combined resource pair.

[6:4]-RAZ/WI
[3:0]F SEL

Selects the resource number, based on the value of F TYPE:

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

When F TYPE is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0].
