20.1.5.9 TCLR Register (offset = 38h) [reset = 0h]
TCLR is shown in Figure 20-17 and described in Table 20-19.
When the TCM field passed from (00) to any other combination then the TCAR_IT_FLAG and the edge
detection logic are cleared. The ST bit of TCLR register may be updated from the OCP interface or reset
due to one-shot overflow. The OCP interface update has the priority.
