Bit: 11

Description: Borrow Status Reset
Bit 11 has a default value of one. Writing a zero to this bit will reset

the Borrow Status bit (register 7, bit 1), but subsequent reads will

return a value of one.
Bit: 12

Description: Counter Equals Comparator Status Reset
Bit 12 has a default value of one. Writing a zero to this bit will reset

the Counter Equals Comparator Status bit (register 7, bit 4) and the

comparator equal interrupt (see register 5, bit 11), but subsequent

reads will return a value of one.
Bit: 13

Description: External Latch Status Reset
Bit 13 has a default value of one. Writing a zero to this bit will reset

the External Latch Status bit (register 7, bit 5) and the external latch

interrupt (see register 5, bit 8), but subsequent reads will return a

valueof one.
Bit: 14

Description: External Count Stop Status Reset
Bit 14 has a default value of one. Writing a zero to this bit will reset

the External Count Stop Status bit (register 7, bit 6) and the external

count stop interrupt (see register 5, bit 9), but subsequent reads will

return a value of one. Note that the Inhibit Counter bit (register 6, bit

9) also must be reset after an external count stop interrupt is

generated.
Bit: 15

Description: External Origin/Clear Status Reset
Bit 15 has a default value of one. Writing a zero to this bit will reset

the External Origin/Clear Status bit (register 7, bit 7) and the Z pulse

and origin interrupt (see register 5, bit 10), but subsequent reads will

return a value of one.
