• Bit 1 - PSR0: Prescaler Reset Timer/Counter0
When this bit is written to one, the Timer/Counter0 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 be read as zero if Timer/Counter0 is clocked by the internal
CPU clock. If this bit is written when Timer/Counter0 is operating in asynchronous
mode, the bit will remain one until the prescaler has been reset.
