16-BIT TIMER
(Cont’d)
CONTROL REGISTER 2 (CR2)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 =
OC1E
Output Compare 1 Pin Enable.
This bit is used only to output the signal from the
timer on the OCMP1 pin (OLV1 in Output Com-
pare mode, both OLV1 and OLV2 in PWM and
one-pulse mode). Whatever the value of the OC1E
bit, the internal Output Compare 1 function of the
timer remains active.
0: OCMP1 pin alternate function disabled (I/O pin
free for general-purpose I/O).
1: OCMP1 pin alternate function enabled.
Bit 6 =
OC2E
Output Compare 2 Pin Enable.
This bit is used only to output the signal from the
timer on the OCMP2 pin (OLV2 in Output Com-
pare mode). Whatever the value of the OC2E bit,
the internal Output Compare 2 function of the timer
remains active.
0: OCMP2 pin alternate function disabled (I/O pin
free for general-purpose I/O).
1: OCMP2 pin alternate function enabled.
Bit 5 =
OPM
One Pulse mode.
0: One Pulse mode is not active.
1: One Pulse mode is active, the ICAP1 pin can be
used to trigger one pulse on the OCMP1 pin; the
active transition is given by the IEDG1 bit. The
length of the generated pulse depends on the
contents of the OC1R register.
Bit 4 =
PWM
Pulse Width Modulation.
0: PWM mode is not active.
1: PWM mode is active, the OCMP1 pin outputs a
programmable cyclic signal; the length of the
pulse depends on the value of OC1R register;
the period depends on the value of OC2R regis-
ter.
Bits 3:2 =
CC[1:0]
Clock Control.
The timer clock mode depends on these bits:
Table 16. Clock Control Bits
Note
: If the external clock pin is not available, pro-
gramming the external clock configuration stops
the counter.
Bit 1 =
IEDG2
Input Edge 2.
This bit determines which type of level transition
on the ICAP2 pin will trigger the capture.
0: A falling edge triggers the capture.
1: A rising edge triggers the capture.
Bit 0 =
EXEDG
External Clock Edge.
This bit determines which type of level transition
on the external clock pin (EXTCLK) will trigger the
counter register.
0: A falling edge triggers the counter register.
1: A rising edge triggers the counter register.
