8-bit Timers/Counters T/C0 and T/C2
AT94KAL Series FPSLIC
Figure 4-26. Timer/Counter2 Prescaler
Special Function I/O Register – SFIOR
• Bits 7..2 - Res: Reserved Bits
These bits are reserved bits in the FPSLIC and are always read as zero.
• 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
the 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; however, the bit will remain as
one until the prescaler has been reset. See
page 99
• 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 the 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.
