8) Time stamp (one time recording) Example
Waiting for next event
Reg − 1E[h]
• Clears EVF bit to “0”.
/INT=”L”?
or
Reg-1E[h] EVF=”1”?
• When event occurs EVF bit is set to ”1”, /INT pin becomes low as interrupt
output.
Reg-20[h]-28[h]
• Reading time stamp data of event occur.
Start
• Set EIE bit to “1” to activate time stamp interrupt function.
An event makes /INT pin interruption output.
• Set ETS bit to “1” to activate time stamp function.
Reg-1F[h]
Reg − 1D[h]
Waiting event
YES
NO
Reg-2B[h]
• Setup EVIN pin input pull-up/pull-down resistor combination.
Reg- 1D[h]
• Clear ETS bit by “0” to inactivate time stamp function.
Reg- 1E[h]
• Clear EVF bit by“0”.
Reg − 1D[h]
• Reset ETS bit to ”0” to inactivate time stamp function.
The reason is to avoid unwanted time stamp during data reading.
