Struct MAPR

pub struct MAPR { /* private fields */ }

AF remap and debug I/O configuration register (MAPR)

Aquired through the Parts struct.

let dp = pac::Peripherals::take().unwrap();
let mut rcc = dp.RCC.constrain();
let mut afio = dp.AFIO.constrain();
function_using_mapr(&mut afio.mapr);

Implementations

impl MAPR

pub fn modify_mapr<F>(&mut self, mod_fn: F)

where F: for<'w> FnOnce(&R, &'w mut W) -> &'w mut W,

pub fn disable_jtag( &mut self, pa15: PA15<Debugger>, pb3: PB3<Debugger>, pb4: PB4<Debugger>, ) -> (PA15<Input<Floating>>, PB3<Input<Floating>>, PB4<Input<Floating>>)

Disables the JTAG to free up pa15, pb3 and pb4 for normal use
