Auto reload register (ATRL)
This is a 12-bit register which is written by software. The ATR register value is automatically
loaded into the upcounter when an overflow occurs. The register value is used to set the
PWM frequency.
Reset value: 0000 0000 (00h)
PWM0 duty cycle register high (DCR0H)
Reset value: 0000 0000 (00h)
PWM0 duty cycle register low (DCR0L)
This 12-bit value is written by software. The high register must be written first.
In PWM mode (OE0=1 in the PWMCR register) the DCR[11:0] bits define the duty cycle of
the PWM0 output signal (see Figure 34). In Output Compare mode, (OE0=0 in the PWMCR
register) they define the value to be compared with the 12-bit upcounter value.
Reset value: 0000 0000 (00h)
