Struct xc2bit::XC2MCSmallIOB

pub struct XC2MCSmallIOB {
    pub zia_mode: XC2IOBZIAMode,
    pub schmitt_trigger: bool,
    pub obuf_uses_ff: bool,
    pub obuf_mode: XC2IOBOBufMode,
    pub termination_enabled: bool,
    pub slew_is_fast: bool,
}

Represents an I/O pin on "small" (32 and 64 macrocell) devices.

Fields

zia_mode: XC2IOBZIAMode

Mux selection for the ZIA input for this pin

schmitt_trigger: bool

Whether the Schmitt trigger is being used on this pin's input

obuf_uses_ff: bool

Selects the source used to drive this pin's output (if the output is enabled). false selects the XOR gate in the macrocell (combinatorial output), and true selects the register output (registered output).

obuf_mode: XC2IOBOBufMode

Selects the output mode for this pin

termination_enabled: bool

Selects if the global termination (bus hold or pull-up) is enabled on this pin

slew_is_fast: bool

Selects if fast slew rate is used on this pin

Methods

impl XC2MCSmallIOB

pub fn encode_jed_internal<T: ?Sized>(&self, fuses: &mut T, start_coord: usize) where
    T: IndexMut<usize, Output = bool>, 

impl XC2MCSmallIOB

pub fn decode_jed_internal<T: ?Sized>(
    fuses: &T,
    start_coord: usize
) -> Result<Self, XC2BitError> where
    T: Index<usize, Output = bool>, 

impl XC2MCSmallIOB

pub fn dump_human_readable<W: Write>(
    &self,
    device: XC2Device,
    my_idx: u32,
    writer: W
) -> Result<(), Error>

Dump a human-readable explanation of the settings for this pin to the given writer object. my_idx must be the index of this I/O pin in the internal numbering scheme.

pub fn to_crbit(&self, device: XC2Device, iob: u32, fuse_array: &mut FuseArray)

Write the crbit representation of the settings for this IO pin to the given fuse_array. device must be the device type this FB was extracted from. iob must be the index of this IO pin.

pub fn from_crbit(
    device: XC2Device,
    iob: u32,
    fuse_array: &FuseArray
) -> Result<Self, XC2BitError>

Read the crbit representation of the settings for this IO pin from the given fuse_array. device must be the device type this FB was extracted from. iob must be the index of this IO pin.

pub fn from_jed(fuses: &[bool], fuse_idx: usize) -> Result<Self, XC2BitError>

Internal function that reads only the IO-related bits from the macrocell configuration

pub fn to_jed(
    &self,
    jed: &mut JEDECFile,
    device: XC2Device,
    fuse_base: usize,
    i: usize
)

Helper that prints the IOB and macrocell configuration on the "small" parts

Trait Implementations

impl Clone for XC2MCSmallIOB

fn clone(&self) -> XC2MCSmallIOB

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for XC2MCSmallIOB

impl Debug for XC2MCSmallIOB

fn fmt(&self, f: &mut Formatter) -> Result
