16-BIT PROGRAMMABLE TIMER

IEDG — Input edge
1 (set)
–
TCAP is positive-going edge sensitive.
0 (clear) –
TCAP is negative-going edge sensitive.
When IEDG is set, a positive-going edge on the TCAP pin will trigger a transfer of the free-running
counter value to the input capture register. When clear, a negative-going edge triggers the transfer.
OLV — Output level
1 (set)
–
A high output level will appear on the TCMP pin.
0 (clear) –
A low output level will appear on the TCMP pin.
When OLV is set, a high output level will be clocked into the output level register by the next
successful output compare, and will appear on the TCMP pin. When clear, it will be a low level that
will appear on the TCMP pin.
6.2.2
Timer status register – TSR
The Timer Status register ($13) contains the status bits for the above three interrupt conditions —
ICF, OCF, TOF.
Accessing the timer status register satises the rst condition required to clear the status bits. The
remaining step is to access the register corresponding to the status bit.
ICF — Input capture ag
1 (set)
–
A valid input capture has occurred.
0 (clear) –
No input capture has occurred.
This bit is set when the selected polarity of edge is detected by the input capture edge detector;
an input capture interrupt will be generated, if ICIE is set. ICF is cleared by reading the TSR and
then the input capture low register at $15.
