DUAL 12-BIT AUTORELOAD TIMER 4 (Cont’d)
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.
BREAK ENABLE REGISTER (BREAKEN)
Read/Write
Reset Value: 0000 0011 (03h)
Bits 7:2 = Reserved, must be kept cleared.
Bit 1 = BREN2 Break Enable for Counter 2
This bit is read/write by software. It enables the
break functionality for Counter2 if BA bit is set in
BREAKCR. It controls PWM2/3 if ENCNTR2 bit is
set.
0: No Break applied for CNTR2
1: Break applied for CNTR2
Bit 0 = BREN1 Break Enable for Counter 1
This bit is read/write by software. It enables the
break functionality for Counter1. If BA bit is set, it
controls PWM0/1 by default, and controls PWM2/3
also if ENCNTR2 bit is reset.
0: No Break applied for CNTR1
1: Break applied for CNTR1
TIMER CONTROL REGISTER2 (ATCSR2)
Read/Write
Reset Value: 0000 0011 (03h)
Bit 7 = FORCE2 Force Counter 2 Overflow
This bit is read/set by software. When set, it loads
FFFh in the CNTR2 register. It is reset by hard-

ware one CPU clock cycle after counter 2 overflow
has occurred.
0 : No effect on CNTR2
1 : Loads FFFh in CNTR2
Note: This bit must not be reset by software
Bit 6 = FORCE1 Force Counter 1 Overflow
This bit is read/set by software. When set, it loads
FFFh in CNTR1 register. It is reset by hardware
one CPU clock cycle after counter 1 overflow has
occurred.
0 : No effect on CNTR1
1 : Loads FFFh in CNTR1
Note: This bit must not be reset by software
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
Bit 4 = OVFIE2 Overflow interrupt 2 enable
This bit is read/write by software and controls the
overflow interrupt of counter2.
0: Overflow interrupt disabled.
1: Overflow interrupt enabled.
Bit 3 = OVF2 Overflow Flag.
This bit is set by hardware and cleared by software
by reading the ATCSR2 register. It indicates the
transition of the counter2 from FFFh to ATR2 val-
ue.
0: No counter overflow occurred
1: Counter overflow occurred
Bit 2 = ENCNTR2 Enable counter2 for PWM2/3
This bit is read/write by software and switches the
PWM2/3 operation to the CNTR2 counter. If this
bit is set, PWM2/3 will be generated using CNTR2.
0: PWM2/3 is generated using CNTR1.
1: PWM2/3 is generated using CNTR2.
Note: Counter 2 gets frozen when the ENCNTR2
bit is reset. When ENCNTR2 is set again, the
counter will restart from the last value.
