Struct stm32f1xx_hal::afio::MAPR

pub struct MAPR { /* fields omitted */ }

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(&mut rcc.apb2);
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
