12.6.4 PRR2 – Power Reduction Register 2
12.6.5 TRXPR – Transceiver Pin Register

ATmega128RFA1
• Bit 3 – PRTIM3 - Power Reduction Timer/Counter3
Writing a logic one to this bit shuts down the Timer/Counter3 module. When the
Timer/Counter3 is enabled, operation will continue like before the shutdown.
• Bit 0 – PRUSART1 - Power Reduction USART1
Writing a logic one to this bit shuts down the USART1 by stopping the clock to the
module. When waking up the USART1 again, the USART1 should be reinitialized to
ensure proper operation.
The Power Reduction Register PRR2 allows to individually disable all four SRAM
blocks. Setting any PRRAM3:0 bit to one will completely switch off (disconnect from the
power supply) the corresponding SRAM block. This enables the application to disable
unused SRAM memory to save power. Every SRAM block can be re-enabled by
reseting the appropriate PRRAM3:0 bit.
• Bit 7:4 – Res3:0 - Reserved Bit
This bit is reserved for future use. A read access always will return zero. A write access
does not modify the content.
• Bit 3 – PRRAM3 - Power Reduction SRAM 3
Setting this bit to one will disable the SRAM block 3. Setting this bit to zero will enable
the SRAM block 3.
• Bit 2 – PRRAM2 - Power Reduction SRAM 2
Setting this bit to one will disable the SRAM block 2. Setting this bit to zero will enable
the SRAM block 2.
• Bit 1 – PRRAM1 - Power Reduction SRAM 1
Setting this bit to one will disable the SRAM block 1. Setting this bit to zero will enable
the SRAM block 1.
• Bit 0 – PRRAM0 - Power Reduction SRAM 0
Setting this bit to one will disable the SRAM block 0. Setting this bit to zero will enable
the SRAM block 0.
