DUAL 12-BIT AUTORELOAD TIMER 3 (Cont’d)
Bit 4 = BPEN Break Pin Enable.
This bit is read/write by software and cleared by
hardware after Reset.
0: Break pin disabled
1: Break pin enabled
Bit 3:0 = PWM[3:0] Break Pattern.
These bits are read/write by software and cleared
by hardware after a reset. They are used to force
the four PWMx output signals into a stable state
when the Break function is active.
PWMx DUTY CYCLE REGISTER HIGH (DCRxH)
Read / Write
Reset Value: 0000 0000 (00h)
PWMx DUTY CYCLE REGISTER LOW (DCRxL)
Read / Write
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved.
Bits 11:0 = DCRx[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
Compare mode, they define the value to be com-
pared with the 12-bit upcounter value.

INPUT CAPTURE REGISTER HIGH (ATICRH)
Read only
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 soft-
ware and cleared by hardware after a reset. The
ATICR register contains captured the value of the
12-bit CNTR1 register when a rising or falling edge
occurs on the ATIC or LTIC pin (depending on
ICS). Capture will only be performed when the ICF
flag is cleared.
TIMER CONTROL REGISTER2 (ATCSR2)
Read/Write
Reset Value: 0000 0011 (03h)
Bits 7:6 = Reserved. Forced by hardware to 0.
Bit 5 = ICS Input Capture Shorted
This bit is read/write by software. It allows the AT-
timer CNTR1 to use the LTIC pin for long input
capture.
0 : ATIC for CNTR1 input capture
1 : LTIC for CNTR1 input capture
