PRPC/D/E/F - Power Reduction Port C/D/E/F Register
• Bit 7:2 - Reserved
These bits are reserved and will always be read as zero. For compatibility with future devices,
always write these bits to zero when this register is written.
• Bit 1 - ADC: Power Reduction ADC
Setting this bit stops the clock to the ADC. The ADC should be disabled before shut down.
• Bit 0 - AC: Power Reduction Analog Comparator
Setting this bit stops the clock to the Analog Comparator. The AC should be disabled before shut
down.
• Bit 7 - Reserved
This bit is reserved and will always be read as zero. For compatibility with future devices, always
write this bit to zero when this register is written.
• Bit 6 - TWI: Two-Wire Interface
Setting this bit stops the clock to the Two-Wire Interface. When the bit is cleared the peripheral
should be reinitialized to ensure proper operation.
• Bit 5 - Reserved
This bit is reserved and will always be read as zero. For compatibility with future devices, always
write this bit to zero when this register is written.
• Bit 4 - USART0
Setting this bit stops the clock to the USART0. When the bit is cleared the peripheral should be
reinitialized to ensure proper operation.
• Bit 3 - SPI: Serial Peripheral Interface
Setting this bit stops the clock to the SPI. When the bit is cleared the peripheral should be reini-
tialized to ensure proper operation.
• Bit 2 - HIRES: Hi-Resolution Extension
Setting this bit stops the clock to the Hi-Resolution Extension for the Timer/Counters. When the
bit is cleared the peripheral should be reinitialized to ensure proper operation.
• Bit 1 - TC1: Timer/Counter 1
Setting this bit stops the clock to the Timer/Counter 1. When the bit is cleared the peripheral will
continue like before the shut down.
