Atmel ATA6612/ATA6613
Timer/Counter1 Control Register C – TCCR1C
Table 6-57.
If external pin modes are used for the Timer/Counter1, transitions on the T1 pin will clock the
counter even if the pin is configured as an output. This feature allows software control of the
counting.
• Bit 5 – Reserved Bit
• Bit 4:3 – WGM13:2: Waveform Generation Mode
• Bit 2:0 – CS12:0: Clock Select
• Bit 7 – FOC1A: Force Output Compare for Channel A
• Bit 6 – FOC1B: Force Output Compare for Channel B
Initial Value
Read/Write
CS12
When the ICR1 is used as TOP value (see description of the WGM13:0 bits located in the
TCCR1A and the TCCR1B Register), the ICP1 is disconnected and consequently the
Input Capture function is disabled.
This bit is reserved for future use. For ensuring compatibility with future devices, this bit
must be written to zero when TCCR1B is written.
See TCCR1A Register description.
The three Clock Select bits select the clock source to be used by the Timer/Counter, see
Figure 6-49 on page 153
The FOC1A/FOC1B bits are only active when the WGM13:0 bits specifies a non-PWM
mode. However, for ensuring compatibility with future devices, these bits must be set to
zero when TCCR1A is written when operating in a PWM mode. When writing a logical one
to the FOC1A/FOC1B bit, an immediate compare match is forced on the Waveform Gen-
eration unit. The OC1A/OC1B output is changed according to its COM1x1:0 bits setting.
Note that the FOC1A/FOC1B bits are implemented as strobes. Therefore it is the value
present in the COM1x1:0 bits that determine the effect of the forced compare.
A FOC1A/FOC1B strobe will not generate any interrupt nor will it clear the timer in Clear
Timer on Compare match (CTC) mode using OCR1A as TOP.
The FOC1A/FOC1B bits are always read as zero.
