Compare Match Output
Unit
Compare Output Mode and
Waveform Generation
98
ATmega16(L)
The Compare Output mode (COM1x1:0) bits have two functions. The Waveform Gener-
ator uses the COM1x1:0 bits for defining the Output Compare (OC1x) state at the next
compare match. Secondly the COM1x1:0 bits control the OC1x pin output source. Fig-
ure 44 shows a simplified schematic of the logic affected by the COM1x1:0 bit setting.
The I/O Registers, I/O bits, and I/O pins in the figure are shown in bold. Only the parts of
the general I/O Port Control Registers (DDR and PORT) that are affected by the
COM1x1:0 bits are shown. When referring to the OC1x state, the reference is for the
internal OC1x Register, not the OC1x pin. If a System Reset occur, the OC1x Register is
reset to “0”.
Figure 44. Compare Match Output Unit, Schematic
The general I/O port function is overridden by the Output Compare (OC1x) from the
Waveform Generator if either of the COM1x1:0 bits are set. However, the OC1x pin
direction (input or output) is still controlled by the Data Direction Register (DDR) for the
port pin. The Data Direction Register bit for the OC1x pin (DDR_OC1x) must be set as
output before the OC1x value is visible on the pin. The port override function is generally
independent of the Waveform Generation mode, but there are some exceptions. Refer
to Table 44, Table 45 and Table 46 for details.
The design of the output compare pin logic allows initialization of the OC1x state before
the output is enabled. Note that some COM1x1:0 bit settings are reserved for certain
modes of operation. See “16-bit Timer/Counter Register Description” on page 109.
The COM1x1:0 bits have no effect on the Input Capture unit.
The Waveform Generator uses the COM1x1:0 bits differently in normal, CTC, and PWM
modes. For all modes, setting the COM1x1:0 = 0 tells the Waveform Generator that no
action on the OC1x Register is to be performed on the next compare match. For com-
pare output actions in the non-PWM modes refer to Table 44 on page 109. For fast
PWM mode refer to Table 45 on page 110, and for phase correct and phase and fre-
quency correct PWM refer to Table 46 on page 110.
A change of the COM1x1:0 bits state will have effect at the first compare match after the
bits are written. For non-PWM modes, the action can be forced to have immediate effect
by using the FOC1x strobe bits.
