Timer/Counter1
Control Register B –

be used to change the output pin value regardless of the timer value. The automatic action pro-
grammed in COM1B1 and COM1B0 takes place as if a compare match had occurred, but no
interrupt is generated. The FOC1B bit always reads as zero. FOC1B is not in use if PWM1B bit
is set.
• Bit 1 – PWM1A: Pulse Width Modulator A Enable
When set (one) this bit enables PWM mode based on comparator OCR1A in Timer/Counter1
and the counter value is reset to $00 in the CPU clock cycle after a compare match with OCR1C
Register value.
• Bit 0 – PWM1B: Pulse Width Modulator B Enable
When set (one) this bit enables PWM mode based on comparator OCR1B in Timer/Counter1
and the counter value is reset to $00 in the CPU clock cycle after a compare match with OCR1C
Register value.
• Bit 7 – CTC1: Clear Timer/Counter on Compare Match
When the CTC1 control bit is set (one), Timer/Counter1 is reset to $00 in the CPU clock cycle
after a compare match with OCR1C Register value. If the control bit is cleared, Timer/Counter1
continues counting and is unaffected by a compare match.
• Bit 6 – PSR1: Prescaler Reset Timer/Counter1
When this bit is set (one), the Timer/Counter prescaler will be reset. The bit will be cleared by
hardware after the operation is performed. Writing a zero to this bit will have no effect. This bit
will always read as zero.
• Bit 5..4 – Res: Reserved Bits
These bits are reserved bits in the ATtiny26(L) and always read as zero.
