Detailed Description

Timer unit with 8Bit counter and 2 output compare unit.

This timer unit is used by following devices: ATMega48/88/168/328.

TCCRxA register contains the following configuration bits (x=timer):

  +------+------+------+------+---+---+-----+-----+
  |COMxA1|COMxA0|COMxB1|COMxB0| - | - |WGMx1|WGMx0|
  +------+------+------+------+---+---+-----+-----+

TCCRxB register contains the following configuration bits (x=timer):

  +-----+-----+---+---+-----+----+----+----+
  |FOCxA|FOCxB| - | - |WGMx2|CSx2|CSx1|CSx0|
  +-----+-----+---+---+-----+----+----+----+
