GTCCR – General

Timer/Counter Control

• Bit 1 – PSR2: Prescaler Reset Timer/Counter2

When this bit is one, the Timer/Counter2 prescaler will be reset. This bit is normally

cleared immediately by hardware. If the bit is written when Timer/Counter2 is operating

in asynchronous 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 “Bit 7

– TSM: Timer/Counter Synchronization Mode” on page 104 for a description of the

Timer/Counter Synchronization mode.
