Register description
Each timer is associated with three control and status registers, and with six pairs of data
registers (16-bit values) relating to the two input captures, the two output compares, the
counter and the alternate counter.
Control register 1 (CR1)
Read/Write
Reset value: 0000 0000 (00h)
Bit 7 = ICIE Input Capture Interrupt Enable.
Bit 6 = OCIE Output Compare Interrupt Enable.
Bit 5 = TOIE Timer Overflow Interrupt Enable.
Bit 4 = FOLV2 Forced Output Compare 2.

7
0: Interrupt is inhibited.
1: A timer interrupt is generated whenever the ICF1 or ICF2 bit of the SR register is set.
0: Interrupt is inhibited.
1: A timer interrupt is generated whenever the OCF1 or OCF2 bit of the SR register is
set.
0: Interrupt is inhibited.
1: A timer interrupt is enabled whenever the TOF bit of the SR register is set.
This bit is set and cleared by software.
0: No effect on the OCMP2 pin.
1:Forces the OLVL2 bit to be copied to the OCMP2 pin, if the OC2E bit is set and even
if there is no successful comparison.
