Struct Syscfg 

pub struct Syscfg { /* private fields */ }

Owns the SYSCFG registers.

Implementations

impl Syscfg

pub fn release(self) -> Syscfg

Returns the peripheral. The clock stays on, since CFGCMPEN also feeds the comparator.

pub fn boot_mode(&self) -> BootMode

Returns the memory the chip booted from, as latched at the last reset.

pub fn set_irq_latency(&mut self, latency: u8)

Holds interrupt entry back to no sooner than latency + 1 cycles of hclk after the interrupt pends. A value above the worst natural latency makes entry take the same time whatever the core was executing; 0, the reset value, enters as early as possible.

pub fn sram_pcef(&self) -> bool

Whether an SRAM parity error has been caught (SRAM_PCEF). Raised only while the check is on, see OptionBytes::sram_parity.

pub fn clear_sram_pcef(&mut self)

Clears SRAM_PCEF.

impl Syscfg

pub fn remap_pa11_pa12<M9: Active, M10: Active>( &mut self, _pa9: Pin<'A', 9, M9>, _pa10: Pin<'A', 10, M10>, ) -> (Pin<'A', 11, Input>, Pin<'A', 12, Input>)

Hands the PA9/PA10 pads over to PA11/PA12, which come back as inputs.

Packages below 32 pins bond one pair or the other on the same two pads, PA9/PA10 after reset.

pub fn unmap_pa11_pa12<M11: Active, M12: Active>( &mut self, _pa11: Pin<'A', 11, M11>, _pa12: Pin<'A', 12, M12>, ) -> (Pin<'A', 9, Input>, Pin<'A', 10, Input>)

Gives the pads back to PA9/PA10, which come back as inputs.
