Operation Status Register Group

The Operation Status Register Group monitors conditions which are part

of the Counter’s normal operation and has a complete set of registers that

• a negative transition filter register (NTR)

• an event register

• an event enable register

Table 3-7 lists the Operation Status Register bits and briefly describes
