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 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 PT1.
