14.3.2.29 Pulse Accumulator B Flag Register (PBFLG)
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.
PBFLG indicates when interrupt conditions have occurred. The flag 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 B System Enable — PBEN is independent from TEN. With timer disabled, the pulse
accumulator can still function unless pulse accumulator is disabled.

0 Interrupt inhibited
1 Interrupt requested if PBOVF is set
Pulse Accumulator B Overflow Flag — This bit is set when the 16-bit pulse accumulator B overflows from
0xFFFF to 0x0000, or when 8-bit pulse accumulator 1 (PAC1) overflows from 0x00FF to 0x0000.
When PACMX = 1, PBOVF bit can also be set if 8-bit pulse accumulator 1 (PAC1) reaches 0x00FF and an active
edge follows on IC1.

the PACB 16-bit pulse accumulator B. When PACB is enabled, the PACN1 and PACN0 registers contents are
respectively the high and low byte of the PACB.
PA1EN and PA0EN control bits in ICPAR have no effect.
The PACB shares the input pin with IC0.
When TFFCA = 1, the flag cannot be cleared via the normal flag clearing
mechanism (writing a one to the flag). Reference
