MC68HC912BL16TS/D
1 = For TFLG1($8E), a read from an input capture or a write to the output compare channel ($90–
$9F) causes the corresponding channel flag, CnF, to be cleared. For TFLG2 ($8F), any access
to the TCNT register ($84, $85) clears the TOF flag. Any access to the PACNT register ($A2,
$A3) clears the PAOVF and PAIF flags in the PAFLG register ($A1). This has the advantage of
eliminating software overhead in a separate clear sequence. Extra care is required to avoid ac-
cidental flag clearing due to unintended accesses.
Read or write anytime.
NOTE
Port T[6] is not bonded to any pin in MC68HC912BL16.
OMn — Output Mode
OLn — Output Level
These eight pairs of control bits are encoded to specify the output action to be taken as a result of a
successful OCn compare. When either OMn or OLn is one, the pin associated with OCn becomes an
output tied to OCn regardless of the state of the associated DDRT bit.
