to the TCNT register ($84, $85) clears the TOF flag. Any
access to the PACN3 and PACN2 registers ($A2, $A3) clears
the PAOVF and PAIF flags in the PAFLG register ($A1). Any
access to the PACN1 and PACN0 registers ($A4, $A5) clears
the PBOVF flag in the PBFLG register ($B1). Any access to the
MCCNT register ($B6, $B7) clears the MCZF flag in the
MCFLG register ($A7). This has the advantage of eliminating
software overhead in a separate clear sequence. Extra care is
required to avoid accidental flag clearing due to unintended
accesses.
