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
consist of the following:

• a positive transition filter register (PTR)
• 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
each bit.
