16-BIT TIMER (Cont’d)
CONTROL REGISTER 2 (TCR2)
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). 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
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
1: OCMP2 pin alternate function enabled.
Bits 5:4 = Reserved, forced by hardware to 0.
Bits 3:2 = CC[1:0] Clock Control.
The timer clock mode depends on these bits:

The three least significant bits are not used.
Bit 7 = Reserved, forced by hardware to 0.
Bit 6 = OCF1 Output Compare Flag 1.
0: No match (reset value).

Bit 5 = TOF Timer Overflow Flag.
0: No timer overflow (reset value).
1: The free running counter rolled over from FFFFh
Note: Reading or writing the ACLR register does
not clear TOF.
