• Bit 2 – PUD: Pull-up Disable
When this bit is set (one), all pull-ups on all ports are disabled. If the bit is cleared (zero),
the pull-ups can be individually enabled as described in the chapter “I/O Ports” on page
115.
• Bit 1 – PSR2: Prescaler Reset Timer/Counter2
When this bit is set (one) the Timer/Counter2 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/Counter2 is clocked by the internal
CPU clock. If this bit is written when Timer/Counter2 is operating in asynchronous
mode. The bit will remain one until the prescaler has been reset. See “Asynchronous
Operation of Timer/Counter2” on page 58 for a detailed description of asynchronous
operation.
• Bit 0 – PSR10: Prescaler Reset Timer/Counter1 and Timer/Counter0
When this bit is set (one) the Timer/Counter1 and 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. Note that Timer/Counter1 and Timer/Counter0 share
the same prescaler and a reset of this prescaler will affect both timers. This bit will
always be read as zero.
