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
PWMX control status register (PWMxCSR)
Reset value: 0000 0000 (00h)
Bits 7:4= Reserved, must be kept cleared.
Bit 3 = OP_EN One Pulse Mode Enable bit
ATR7
15
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)
1: PWM mode enabled
