• When an overflow occurs, the value of TAUBnCDRm remains unchanged
and TAUBnCSRm.TAUBnOVF remains = 0.
• Upon detection of the next valid TAUBnTTINm input edge, the value of
TAUBnCNTm is loaded into TAUBnCDRm and TAUBnCSRm.TAUBnOVF is
set to1.
• Upon detection of the next valid TAUBnTTINm input edge with no overflow
occurring, TAUBnCSRm.TAUBnOVF is cleared to 0.

• Upon detection of the next valid TAUBnTTINm input edge, the value of
TAUBnCNTm is loaded into TAUBnCDRm.
• TAUBnCSRm.TAUBnOVF is cleared by setting TAUBnCSCm.TAUBnCLOV
bit to 1.
