Standard Timer (TIM)
12.3.8 Timer Interrupt Flag Registers
Read: Anytime
Write: Used in the clearing mechanism; set bits cause corresponding bits to
TFLG1 indicates when interrupt conditions have occurred. To clear a bit in the flag register, write a 1 to
the bit. Writing a logic 0 does not affect current status of the bit.
When TFFCA bit in TSCR register is set, a read from an input capture or a write into an output compare
channel ($90–$9F) causes the corresponding channel flag CnF to be cleared.
C7F–C0F — Input Capture/Output Compare Channel n Flag
Read: Anytime
Write: Used in the clearing mechanism; set bits cause corresponding bits to
TFLG2 indicates when interrupt conditions have occurred. To clear a bit in the flag register, set the bit to 1.
Any access to TCNT clears TFLG2 register, if the TFFCA bit in TSCR register is set.
TOF — Timer Overflow Flag
148
Set when 16-bit free-running timer overflows from $FFFF to $0000. This bit is cleared automatically by
a write to the TFLG2 register with bit 7 set. For additional information, see the TCRE control bit
