Bit 0
PWM0OUT: PWM output control bit.
0 = Disable PWM output.
1 = Enable PWM output. PWM duty controlled by TC0OUT, ALOAD0 bits.
Bit 1
TC0OUT: TC0 time out toggle signal output control bit. Only valid when PWM0OUT = 0.
0 = Disable, P5.3 is I/O function.
1 = Enable, P5.3 is output TC0OUT signal.
Bit 2
ALOAD0: Auto-reload control bit. Only valid when PWM0OUT = 0.
0 = Disable TC0 auto-reload function.
1 = Enable TC0 auto-reload function.
Bit 3
TC0CKS: TC0 clock source select bit.
0 = Internal clock (Fcpu or Fosc).
1 = External clock from P0.0/INT0 pin.
Bit [6:4]
TC0RATE[2:0]: TC0 internal clock select bits.
000 = fcpu/256.
001 = fcpu/128.
…
110 = fcpu/4.
111 = fcpu/2.
Bit 7
TC0ENB: TC0 counter control bit.
0 = Disable TC0 timer.
1 = Enable TC0 timer.
’ Note: When TC0CKS=1, TC0 became an external event counter and TC0RATE is useless. No more P0.0
interrupt request will be raised. (P0.0IRQ will be always 0).
