The CNTCVL register characteristics are:

Purpose

Reads or writes the lower 32 bits of the current counter value.

Usage constraints

The read-only programming interface can read but not write to this register. The control interface must clear the CNTCR.EN bit before writing to this register.

Attributes

See the register summary in Table 3.246.

Figure 3.224 shows the bit assignments.
