3.16.30. Extended External Input Selection Register, ETMEXTINSELR

The ETMEXTINSELR characteristics are:


Selects the extended external inputs. See Extended external inputs.

Usage constraints

There are no usage constraints.


Available in all PTM implementations.

The number of extended external input selectors:

  • is implementation defined

  • is specified by ETMCCER bits [2:0]

  • can be zero.

See Configuration Code Extension Register, ETMCCER:

If the PTM implements fewer than four extended external input selectors then the unused extended external input selector fields in the ETMEXTINSELR are RAZ/WI.

If the PTM does not implement any extended external input selectors then the ETMEXTINSELR is RAZ/WI.


See the register summary in Table 3.16.
