• Bits 7..4 – Res: Reserved Bits
These bits are reserved bits in the ATtiny26(L) and always read as zero.
• Bit 3 – PSR0: Prescaler Reset Timer/Counter0
When this bit is set (one), the prescaler of the Timer/Counter0 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 be read as zero.
• Bits 2, 1, 0 – CS02, CS01, CS00: Clock Select0, Bit 2, 1, and 0
The Clock Select0 bits 2, 1, and 0 define the prescaling source of Timer0.
