SwitchStatus

Struct SwitchStatus 

Source
pub struct SwitchStatus {
    pub raw: [u8; 64],
}
Expand description

64-byte SD function-switch status, returned in the data phase of CMD6.

See SD Physical Layer spec section 4.3.10 (Switch Function). Field numbering uses the spec’s bit-435..=0 convention but accessors here are expressed in byte offsets within raw[0..64] for clarity.

Fields§

§raw: [u8; 64]

Implementations§

Source§

impl SwitchStatus

Source

pub fn from_raw(raw: [u8; 64]) -> Self

Source

pub fn selected_function(&self, group: u8) -> u8

Selected function for group (1-based, 1..=6) after a switch operation. 0xF means the group is not supported by the card.

Group 1 selection lives in the low nibble of byte 16; group 2 in the high nibble of the same byte; group 3 in the low nibble of byte 15; and so on, paired big-endian over bytes 14..=16.

Source

pub fn high_speed_active(&self) -> bool

Returns true iff group 1 reports high-speed (function 1) selected.

Source

pub fn access_mode_supported(&self, function: u8) -> bool

Returns true iff SD access-mode group 1 advertises function.

The support bitmap for group 1 is carried in byte 13 in the 64-byte switch status block; bit n means function n is selectable.
