14.3.2.16 Pulse Accumulator A Flag Register (PAFLG)
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.
PAFLG 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

Pulse Accumulator A Overflow Flag — Set when the 16-bit pulse accumulator A overflows from 0xFFFF to
0x0000, or when 8-bit pulse accumulator 3 (PAC3) overflows from 0x00FF to 0x0000.
When PACMX = 1, PAOVF bit can also be set if 8-bit pulse accumulator 3 (PAC3) reaches 0x00FF followed by
an active edge on IC3.
Pulse Accumulator Input edge Flag — Set when the selected edge is detected at the IC7 input pin. In event
mode the event edge triggers PAIF and in gated time accumulation mode the trailing edge of the gate signal at
the IC7 input pin triggers PAIF.
