ATtiny87/ATtiny167
General Timer/Counter Control Register – GTCCR
• Bit 1 – PSR0: Prescaler Reset Timer/Counter0
When this bit is one, the Timer/Counter0 prescaler will be reset. This bit is normally cleared
immediately by hardware. If the bit is written when Timer/Counter0 is operating in asynchro-
nous mode, the bit will remain one until the prescaler has been reset. The bit will not be
cleared by hardware if the TSM bit is set. Refer to the description of the
Timer/Counter Synchronization Mode” on page 109
