Detailed Description

Timer unit with 16Bit counter and 2 output compare units and 2 config registers.

This timer unit is used by following devices: ATMega16, AT90S8515.

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

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

On AT90S8515 FOCx bits are not available, WGMxy bits are named PWMxy!

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

  +-----+-----+---+-----+-----+----+----+----+
  |ICNCx|ICESx| - |WGMx3|WGMx2|CSx2|CSx1|CSx0|
  +-----+-----+---+-----+-----+----+----+----+

On AT90S8515 WGMx3 bit is not available, WGMx2 bit is named CTCx!
