Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved.
Bits 11:0 = DCR[11:0] PWMx Duty Cycle Value
This 12-bit value is written by software. It defines the duty cycle of the corresponding PWM
output signal (see
In PWM mode (OEx=1 in the PWMCR register) the DCR[11:0] bits define the duty cycle of
the PWMx output signal (see

Reset Value: 0000 0000 (00h)
Input capture register low (ATICRL)
Read only
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved.
Bits 11:0 = ICR[11:0] Input Capture Data.
This is a 12-bit register which is readable by software and cleared by hardware after a reset.
The ATICR register contains captured the value of the 12-bit CNTR register when a rising or
falling edge occurs on the ATIC pin. Capture will only be performed when the ICF flag is
cleared.
