Register Description – Power Reduction
PRGEN - General Power Reduction Register
Table 8-2.
• Bit 1 - SEN: Sleep Enable
This bit must be set to make the MCU enter the selected sleep mode when the SLEEP instruc-
tion is executed. To avoid unintentional entering of sleep modes, it is recommended to write
SEN just before executing the SLEEP instruction, and clearing it immediately after waking up.
• Bit 7:5 - 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 4 - AES: AES Module
Setting this bit stops the clock to the AES module. When the bit is cleared the peripheral should
be reinitialized to ensure proper operation.
• Bit 3 - EBI: External Bus Interface
Setting this bit stops the clock to the External Bus Interface. When the bit is cleared the periph-
eral should be reinitialized to ensure proper operation. Note that the EBI is not present for all
devices.
• Bit 2 - RTC: Real-Time Counter
Setting this stops the clock to the Real Time Counter. When the bit is cleared the peripheral
should be reinitialized to ensure proper operation.
• Bit 1 - EVSYS: Event System
Setting this stops the clock to the Event System. When the bit is cleared the module will continue
like before the shutdown.
• Bit 0 - DMA: DMA Controller
Setting this stops the clock to the DMA Controller. This bit can only be set if the DMA Controller
is disabled.
