TIMER CONTROL STATUS REGISTER (ATC-
SR)
Read / Write
Reset Value: 0000 0000 (00h)
Bit 7:5 = Reserved, must be kept cleared.
Bit 4:3 = CK[1:0] Counter Clock Selection.
These bits are set and cleared by software and
cleared by hardware after a reset. They select the
clock frequency of the counter.
Bit 2 = OVF Overflow Flag.
This bit is set by hardware and cleared by software
by reading the ATCSR register. It indicates the
transition of the counter from FFFh to ATR value.
0: No counter overflow occurred
1: Counter overflow occurred
Caution:
When set, the OVF bit stays high for 1 f
cycle, (up to 1ms depending on the clock selec-
tion).
Bit 1 = OVFIE Overflow Interrupt Enable.
This bit is read/write by software and cleared by
hardware after a reset.
0: OVF interrupt disabled
1: OVF interrupt enabled
Bit 0 = CMPIE Compare Interrupt Enable.
This bit is read/write by software and clear by

COUNTER REGISTER HIGH (CNTRH)

Reset Value: 0000 0000 (00h)
COUNTER REGISTER LOW (CNTRL)
Read only
Reset Value: 0000 0000 (00h)
Bits 15:12 = Reserved, must be kept cleared.
Bits 11:0 = CNTR[11:0] Counter Value.
This 12-bit register is read by software and cleared
by hardware after a reset. The counter is incre-
mented continuously as soon as a counter clock is
selected. To obtain the 12-bit value, software
should read the counter value in two consecutive
read operations. The CNTRH register can be in-
cremented between the two reads, and in order to
be accurate when f
should take this into account when CNTRL and
CNTRH are read. If CNTRL is close to its highest
value, CNTRH could be incremented before it is
read.
When a counter overflow occurs, the counter re-
starts from the value specified in the ATR register.
