Aus dem Datenblatt:
--------------------------------------------------
36.7.1 TC Channel Control Register
Name: TC_CCRx [x=0..2]
Access: Write-only

• CLKEN: Counter Clock Enable Command
0: No effect.
1: Enables the clock if CLKDIS is not 1.

• CLKDIS: Counter Clock Disable Command
0: No effect.
1: Disables the clock.

• SWTRG: Software Trigger Command
0: No effect.
1: A software trigger is performed: the counter is
reset and the clock is started.

Ich tippe mal auf Bit 2, SWTRG, das tut was du willst.

Did you find the solution to this problem.
I'm not able to reset the counter, REG_TC0_CV0, without moving the 
encoder. Then it resets. Otherwise it doesn't
This is the Arduino code I'm using:

void setup()
{
  Serial.begin(38400);
  REG_PIOB_PDR = digitalPinToBitMask(2);
  REG_PIOB_ABSR |= digitalPinToBitMask(2);
  REG_PIOB_PDR = digitalPinToBitMask(13);
  REG_PIOB_ABSR |= digitalPinToBitMask(13);
  REG_PMC_PCER0 = (1<<27);
  REG_TC0_CMR0 = 5;
  REG_TC0_BMR = (1<<9)|(1<<8)|(1<<12);
}

void loop()
{
  int32_t pulseCount;
  REG_TC0_CCR0 = TC_CCR_CLKEN | TC_CCR_SWTRG;
  for(int i = 0; i < 50; i++)
  {
    pulseCount = REG_TC0_CV0; //read counter register
    Serial.print(i);
    Serial.print(' ');
    Serial.println(pulseCount);
    delay(100);
  }
  REG_TC0_CCR0 = TC_CCR_CLKDIS;  //disable clock
  REG_TC0_CCR0 = TC_CCR_CLKEN | TC_CCR_SWTRG;  //enable clock and reset 
counter
  while(REG_TC0_CV0);
  for(int i = 0; i < 50; i++)
  {
    pulseCount = REG_TC0_CV0; //read counter register
    Serial.print(i);
    Serial.print(' ');
    Serial.println(pulseCount);
    delay(100);
  }
  while(1);
}
