14.3.2.12 Main Timer Interrupt Flag 1 (TFLG1)
Read: Anytime
Write used in the flag clearing mechanism. Writing a one to the flag clears the flag. Writing a zero will not
affect the current status of the bit.
All bits reset to zero.
TFLG1 indicates when interrupt conditions have occurred. The flags can be cleared via the normal flag
clearing mechanism (writing a one to the flag) or via the fast flag clearing mechanism (reference TFFCA
bit in
Use of the TFMOD bit in the ICSYS register in conjunction with the use of the ICOVW register allows a
timer interrupt to be generated after capturing two values in the capture and holding registers, instead of
generating an interrupt for every capture.

Input Capture/Output Compare Channel “x” Flag — A CxF flag is set when a corresponding input capture or
output compare is detected. C0F can also be set by 16-bit Pulse Accumulator B (PACB). C3F–C0F can also be
set by 8-bit pulse accumulators PAC3–PAC0.
If the delay counter is enabled, the CxF flag will not be set until after the delay.
