8266A-MCU Wireless-12/09
Combined with the WGM11:0 bits found in the TCCR1A Register, these bits control the
counting sequence of the counter, the source for maximum (TOP) counter value, and
what type of waveform generation to be used. Modes of operation supported by the
Timer/Counter unit are: Normal mode (counter), Clear Timer on Compare match (CTC)
mode, and three types of Pulse Width Modulation (PWM) modes. For more information
on the different modes see section "Modes of Operation".
Table 18-10 WGM1 Register Bits
• Bit 2:0 – CS12:10 - Clock Select
The three clock select bits select the clock source to be used by the Timer/Counter1
according to the following table. 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.
