16-BIT TIMER
(Cont’d)
5.3.7 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 al-
ternate counter.
CONTROL REGISTER 1 (CR1)
Read/Write
Reset Value: 0000 0000 (00h)

Bit 7 =
ICIE
Input Capture Interrupt Enable.
0: Interrupt is inhibited.
1: A timer interrupt is generated whenever the
ICF1 or ICF2 bit of the SR register is set.
Bit 6 =
OCIE
Output Compare Interrupt Enable.
0: Interrupt is inhibited.
1: A timer interrupt is generated whenever the
OCF1 or OCF2 bit of the SR register is set.
Bit 5 =
TOIE
Timer Overflow Interrupt Enable.
0: Interrupt is inhibited.
1: A timer interrupt is enabled whenever the TOF
bit of the SR register is set.
Bit 4 =
FOLV2
Forced Output Compare 2.
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.
Bit 3 =
FOLV1
Forced Output Compare 1.
This bit is set and cleared by software.
0: No effect on the OCMP1 pin.
1: Forces OLVL1 to be copied to the OCMP1 pin, if
the OC1E bit is set and even if there is no suc-
cessful comparison.
Bit 2 =
OLVL2
Output Level 2.
This bit is copied to the OCMP2 pin whenever a
successful comparison occurs with the OC2R reg-
ister and OCxE is set in the CR2 register. This val-
ue is copied to the OCMP1 pin in One Pulse mode
and Pulse Width Modulation mode.
Bit 1 =
IEDG1
Input Edge 1.
This bit determines which type of level transition
on the ICAP1 pin will trigger the capture.
0: A falling edge triggers the capture.
1: A rising edge triggers the capture.
Bit 0 =
OLVL1
Output Level 1.
The OLVL1 bit is copied to the OCMP1 pin when-
ever a successful comparison occurs with the
OC1R register and the OC1E bit is set in the CR2
register.
