12-BIT AUTORELOAD TIMER (Cont’d)
AUTORELOAD REGISTER (ATRH)
Read / Write
Reset Value: 0000 0000 (00h)
AUTORELOAD REGISTER (ATRL)
Read / Write
Reset Value: 0000 0000 (00h)
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.
PWM OUTPUT CONTROL REGISTER
(PWMCR)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:0 = OE[3:0] PWMx output enable.
These bits are set and cleared by software and
cleared by hardware after a reset.
0: PWM mode disabled. PWMx output alternate
1: PWM mode enabled
ATR7
15
function disabled: I/O pin free for general pur-
pose I/O after an overflow event.

PWMx CONTROL STATUS REGISTER
(PWMxCSR)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 7:2= Reserved, must be kept cleared.
Bit 1 = OPx PWMx Output Polarity.
This bit is read/write by software and cleared by
hardware after a reset. This bit selects the polarity
of the PWM signal.
0: The PWM signal is not inverted.
1: The PWM signal is inverted.
Bit 0 = CMPFx PWMx Compare Flag.
This bit is set by hardware and cleared by software
by reading the PWMxCSR register. It indicates
that the upcounter value matches the DCRx regis-
ter value.
0: Upcounter value does not match DCR value.
1: Upcounter value matches DCR value.
BREAK CONTROL REGISTER (BREAKCR)
Read/Write
Reset Value: 0000 0000 (00h)
Bits 7:6 = Reserved. Forced by hardware to 0.
Bit 5 = BA Break Active.
This bit is read/write by software, cleared by hard-
ware after reset and set by hardware when the
BREAK pin is low. It activates/deactivates the
Break function.
0: Break not active
1: Break active
