8.3.3 TC0M MODE REGISTER

TC0M is TC0 timer mode control register to configure TC0 operating mode including TC0 pre-scalar, clock source,

PWM function…These configurations must be setup completely before enabling TC0 timer.

Bit 0

PWM0OUT: PWM output control bit.

0 = Disable PWM output function, and P5.1 is GPIO mode.

1 = Enable PWM output function, and P5.1 outputs PWM signal.

Bit 2

TC0CKS0: TC0 clock source select bit.

0 = Fcpu.

1 = Fhosc.

Bit 3

TC0CKS1: TC0 clock source select bit.

0 = Internal clock (Fcpu and Fhosc controlled by TC0CKS0 bit).

1 = External input pin (P0.0/INT0) and enable event counter function. TC0rate[2:0] bits are useless.

Bit [6:4]

TC0RATE[2:0]: TC0 timer clock source select bits.

TC0CKS0=0 -> 000 = Fcpu/128, 001 = Fcpu/64, 010 = Fcpu/32, 011 = Fcpu/16, 100 = Fcpu/8, 101 = Fcpu/4,

110 = Fcpu/2,111 = Fcpu/1.

TC0CKS0=1 -> 000 = Fhosc/128, 001 = Fhosc/64, 010 = Fhosc/32, 011 = Fhosc/16, 100 = Fhosc/8,

101 = Fhosc/4, 110 = Fhosc/2,111 = Fhosc/1.

Bit 7

TC0ENB: TC0 counter control bit.

0 = Disable TC0 timer.

1 = Enable TC0 timer.

8.3.4 TC0C COUNTING REGISTER

TC0C is TC0 8-bit counter. When TC0C overflow occurs, the TC0IRQ flag is set as

“1” and cleared by program. The

TC0C decides TC0 interval time through below equation to calculate a correct value. It is necessary to write the correct

value to TC0C register and TC0R register first time, and then enable TC0 timer to make sure the fist cycle correct.

After one TC0 overflow occurs, the TC0C register is loaded a correct value from TC0R register automatically, not

program.

The equation of TC0C initial value is as following.

TC0C initial value = 256 - (TC0 interrupt interval time * TC0 clock rate)
