Register description
Timer control status register (ATCSR)
Reset value: 0x00 0000 (x0h)
Bit 7 = Reserved
Bit 6 = ICF Input Capture flag
Bit 5 = ICIE IC Interrupt Enable bit
Bits 4:3 = CK[1:0] Counter Clock Selection bits
Table 37.
Bit 2 = OVF1 Overflow flag
Bit 1 = OVFIE1 Overflow Interrupt Enable bit
This Bit is set by hardware and cleared by software by reading the ATICR register (a
read access to ATICRH or ATICRL clears this flag). Writing to this bit does not change
the bit value.
0: No input capture
1: An input capture has occurred
This bit is set and cleared by software.
0: Input Capture Interrupt Disabled
1: Input Capture Interrupt Enabled
These bits are set and cleared by software and cleared by hardware after a reset. they
select the clock frequency of the counter.
This bit is set by hardware and cleared by software by reading the ATCSR register. It
indicates the transition of the Counter1 CNTR1 from FFFh to ATR1 value.
0: No Counter Overflow Occurred
1: Counter Overflow Occurred
This bit is read/write by software and cleared by hardware after a reset.
0: Overflow Interrupt Disabled.
1: Overflow Interrupt Enabled.
