AUTO RELOAD REGISTER (ATRL)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved, must be kept cleared.
Bits 11:0 = ATR[11:0] Autoreload Register.
This is a 12-bit register which is written by soft-
ware. The ATR register value is automatically
loaded into the upcounter when an overflow oc-
curs. The register value is used to set the PWM
frequency.

PWM0 DUTY CYCLE REGISTER LOW (DCR0L)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved, must be kept cleared.
Bits 11:0 = DCR[11:0] PWMx Duty Cycle Value
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
Compare mode, (OE0=0 in the PWMCR register)
they define the value to be compared with the 12-
bit upcounter value.
PWM0
(PWM0CSR)
Read / Write
Reset Value: 0000 0000 (00h)
Bit 7:2= Reserved, must be kept cleared.
Bit 1 = OP0 PWM0 Output Polarity.
This bit is read/write by software and cleared by
hardware after a reset. This bit selects the polarity
of the PWM0 signal.
0: The PWM0 signal is not inverted.
1: The PWM0 signal is inverted.
Bit 0 = CMPF0 PWM0 Compare Flag.
This bit is set by hardware and cleared by software
by reading the PWM0CSR register. It indicates
that the upcounter value matches the DCR0 regis-
ter value.
0: Upcounter value does not match DCR value.
1: Upcounter value matches DCR value.
