Power Reduction TWI1
Writing a logic one to this bit shuts down the TWI1 by stopping the clock to the module. When waking up the TWI1 again, the TWI1 should be re initialized to ensure proper operation.
Power Reduction PTC
Writing a logic one to this bit shuts down the PTC module. When the PTC is enabled, operation will continue like before the shutdown.
Power Reduction Timer/Counter4
Writing a logic one to this bit shuts down the Timer/Counter4 module. When the Timer/Counter4 is enabled, operation will continue like before the shutdown.
Power Reduction Serial Peripheral Interface 1
If using debugWIRE On-chip Debug System, this bit should not be written to one. Writing a logic one to this bit shuts down the Serial Peripheral Interface1 by stopping the clock to the module. When waking up the SPI1 again, the SPI1 should be re initialized to ensure proper operation.
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.
