Struct UpdateFlags 

#[non_exhaustive]
pub struct UpdateFlags {
    pub status_update: bool,
    pub ced_update: bool,
    pub rr_test: bool,
    pub source_test_update: bool,
    pub frl_start: bool,
    pub flt_update: bool,
    pub rsed_update: bool,
}

Decoded content of Update_0 (0x10).

Flags are set by the sink to notify the source of state changes. The source reads them with Scdc::read_update_flags and clears the ones it has handled with Scdc::clear_update_flags (write-1-to-clear), which takes a ClearableUpdateFlags: every flag but RR_Test. clearable gives the flags just read in that form. Update_1 (0x11) defines no fields and is not accessed. The default has no flag set.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

status_update: bool

Bit 0: general status has changed.

ced_update: bool

Bit 1: CED counters have been updated; re-read the ERR_DET registers.

rr_test: bool

Bit 2: read request test, owned by the sink. The source does not clear it, so ClearableUpdateFlags has no field for it.

source_test_update: bool

Bit 3: the sink has written Source_Test_Configuration (0x35).

frl_start: bool

Bit 4: link training passed; the source may start FRL transmission.

flt_update: bool

Bit 5: the per-lane link training pattern requests have changed.

rsed_update: bool

Bit 6: the Reed-Solomon correction count has been updated.

Implementations

impl UpdateFlags

pub const fn new( status_update: bool, ced_update: bool, rr_test: bool, source_test_update: bool, frl_start: bool, flt_update: bool, rsed_update: bool, ) -> UpdateFlags

Constructs UpdateFlags from the Update_0 flags, in bit order.

pub const fn clearable(self) -> ClearableUpdateFlags

These flags as a clear: every flag but RR_Test, which the source does not clear. scdc.clear_update_flags(flags.clearable()) acknowledges every flag just read.
