Bits 11:0 = CNTR1[11:0] Counter value
Autoreload register (ATR1H)
Reset value: 0000 0000 (00h)
Autoreload register (ATR1L)
Reset value: 0000 0000 (00h)
Bits 11:0 = ATR1[11:0] Autoreload register 1:
This is a 12-bit register which is written by software. The ATR1 register value is
automatically loaded into the upcounter CNTR1 when an overflow occurs. The register
value is used to set the PWM frequency.
PWM output control register (PWMCR)
Reset value: 0000 0000 (00h)
Bits 7:0 = OE[3:0] PWMx output enable bits

This 12-bit register is read by software and cleared by hardware after a reset. The
counter CNTR1 increments continuously as soon as a counter clock is selected. To
obtain the 12-bit value, software should read the counter value in two consecutive read
operations. As there is no latch, it is recommended to read LSB first. In this case,
CNTR1H can be incremented between the two read operations and to have an
accurate result when f
close to FFh are read.
When a counter overflow occurs, the counter restarts from the value specified in the
ATR1 register.
These bits are set and cleared by software and cleared by hardware after a reset.
0: PWM mode disabled. PWMx Output Alternate function disabled (I/O pin free for
general purpose I/O)
