impl Cr1

pub const fn lpms(&self) -> Lpms

These bits select the low-power mode entered when the CPU enters the Deepsleep mode. 000: Stop 0 mode 001: Stop 1 mode 010: Stop 2 mode 011: Stop 3 mode 100-101: Standby mode 110-111: Shutdown mode.

pub fn set_lpms(&mut self, val: Lpms)

These bits select the low-power mode entered when the CPU enters the Deepsleep mode. 000: Stop 0 mode 001: Stop 1 mode 010: Stop 2 mode 011: Stop 3 mode 100-101: Standby mode 110-111: Shutdown mode.

pub const fn rrsb1(&self) -> bool

This bit is used to keep the SRAM2 page 1 content in Standby mode. The SRAM2 page 1 corresponds to the first 8 Kbytes of the SRAM2 (from SRAM2 base address to SRAM2 base address + 0x1FFF). 0: SRAM2 page1 content not retained in Standby mode 1: SRAM2 page1 content retained in Standby mode Note: This bit has no effect in Shutdown mode.

pub fn set_rrsb1(&mut self, val: bool)

This bit is used to keep the SRAM2 page 1 content in Standby mode. The SRAM2 page 1 corresponds to the first 8 Kbytes of the SRAM2 (from SRAM2 base address to SRAM2 base address + 0x1FFF). 0: SRAM2 page1 content not retained in Standby mode 1: SRAM2 page1 content retained in Standby mode Note: This bit has no effect in Shutdown mode.

pub const fn rrsb2(&self) -> bool

This bit is used to keep the SRAM2 page 2 content in Standby mode. The SRAM2 page 2 corresponds to the 24 Kbytes of the SRAM2 (from SRAM2 base address + 0x2000 to SRAM2 base address + 0x7FFF). 0: SRAM2 page2 content not retained in Standby mode 1: SRAM2 page2 content retained in Standby mode Note: This bit has no effect in Shutdown mode.

pub fn set_rrsb2(&mut self, val: bool)

This bit is used to keep the SRAM2 page 2 content in Standby mode. The SRAM2 page 2 corresponds to the 24 Kbytes of the SRAM2 (from SRAM2 base address + 0x2000 to SRAM2 base address + 0x7FFF). 0: SRAM2 page2 content not retained in Standby mode 1: SRAM2 page2 content retained in Standby mode Note: This bit has no effect in Shutdown mode.

pub const fn rrsb3(&self) -> bool

This bit is used to keep the SRAM2 page 3 content in Standby mode. The SRAM2 page 3 corresponds to the last 32 Kbytes of the SRAM2 (from SRAM2 base address + 0x8000 to SRAM2 base address + 0xFFFF). 0: SRAM2 page3 content not retained in Standby mode 1: SRAM2 page3 content retained in Standby mode Note: This bit has no effect in Shutdown mode.

pub fn set_rrsb3(&mut self, val: bool)

This bit is used to keep the SRAM2 page 3 content in Standby mode. The SRAM2 page 3 corresponds to the last 32 Kbytes of the SRAM2 (from SRAM2 base address + 0x8000 to SRAM2 base address + 0xFFFF). 0: SRAM2 page3 content not retained in Standby mode 1: SRAM2 page3 content retained in Standby mode Note: This bit has no effect in Shutdown mode.

pub const fn ulpmen(&self) -> bool

This bit is used to reduce the consumption by configuring the BOR in discontinuous mode. This bit has effect only when the BOR level 0 is selected and when the device is in Standby mode. This bit must be set to reach the lowest power consumption in Standby mode. 0: BOR level 0 operating in continuous (normal) mode in Standby mode 1: BOR level 0 operating in discontinuous (ultra-low power) mode in Standby mode.

pub fn set_ulpmen(&mut self, val: bool)

This bit is used to reduce the consumption by configuring the BOR in discontinuous mode. This bit has effect only when the BOR level 0 is selected and when the device is in Standby mode. This bit must be set to reach the lowest power consumption in Standby mode. 0: BOR level 0 operating in continuous (normal) mode in Standby mode 1: BOR level 0 operating in discontinuous (ultra-low power) mode in Standby mode.

pub const fn sram1pd(&self) -> Srampd

This bit is used to reduce the consumption by powering off the SRAM1. 0: SRAM1 powered on 1: SRAM1 powered off Note: When this bit is cleared to 0, wait for more than 1.6us before accessing the SRAM.

pub fn set_sram1pd(&mut self, val: Srampd)

This bit is used to reduce the consumption by powering off the SRAM1. 0: SRAM1 powered on 1: SRAM1 powered off Note: When this bit is cleared to 0, wait for more than 1.6us before accessing the SRAM.

pub const fn sram2pd(&self) -> Srampd

This bit is used to reduce the consumption by powering off the SRAM2. 0: SRAM2 powered on 1: SRAM2 powered off Note: When this bit is cleared to 0, wait for more than 1.6us before accessing the SRAM.

pub fn set_sram2pd(&mut self, val: Srampd)

This bit is used to reduce the consumption by powering off the SRAM2. 0: SRAM2 powered on 1: SRAM2 powered off Note: When this bit is cleared to 0, wait for more than 1.6us before accessing the SRAM.
