Counter Control Register 0
The TRCCNTCTLR0 characteristics are:
- Purpose
-
Controls the counter.
- Usage constraints
-
Accepts writes only when the trace unit is disabled.
- Configurations
-
Available in all configurations.
- Attributes
-
See the register summary in Table 13.3.
Figure 13.23 shows the TRCCNTCTLR0 bit assignments.
Table 13.24 shows the TRCCNTCTLR0 bit assignments.
Bits | Name | Function |
---|---|---|
[31:17] | - | Reserved, res0. |
[16] | RLDSELF |
Defines whether the counter reloads when it reaches zero:
|
[15] | RLDTYPE |
Selects the resource type for the reload:
|
[14:12] | - | Reserved, res0. |
[11:8] | RLDSEL |
Selects the resource number, based on the value of RLDTYPE: When RLDTYPE is 0, selects a single selected resource from 0-15 defined by bits[3:0]. When RLDTYPE is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0]. |
[7] | CNTTYPE |
Selects the resource type for the counter:
|
[6:4] | - | Reserved, res0. |
[3:0] | CNTSEL |
Selects the resource number, based on the value of CNTTYPE: When CNTTYPE is 0, selects a single selected resource from 0-15 defined by bits[3:0]. When CNTTYPE is 1, selects a Boolean combined resource pair from 0-7 defined by bits[2:0]. |
The TRCCNTCTLR0 can be accessed through the internal memory-mapped
interface and the external debug interface, offset 0x150
