@returns The bounds of this segment descriptor; will be either [0, limit] or [limit, INT_MAX] depending on descriptor type. Accesses must be `>= bound

! Produces a byte buffer where the contents of @c data are serialised into bytes If @c msb_first is @c true then each byte is expected to be dese

! @returns 0 if this byte access wants the low part of a 16-bit word; 8 if it wants the high part, i.e. take a word quantity and shift it right b

@returns @c 0x20 if this sprite should generate collisions; @c 0x00 otherwise.

@returns the number of cycles until the next sequence-point-based flush, if the embedded object supports sequence points; @c LocalTimeScale() otherwis

@returns The default segment to use for this access.

Indicates whether a flush has occurred since the last call to did_flush().

Indicates that the PC was altered by the instruction.

DiskController::Delegate

@returns @c true if no actions are enqueued; @c false otherwise.

@returns A bitmask of events that occurred during the last shift.

Issues a request to the AY to perform all processing up to the current time.

Flushes all accumulated time. This does not affect this actor's record of when the next sequence point will occur.

! Returns the current output position; while in retrace this will go down towards 0, while in scan it will go upward. @returns The current outp

! @returns the height of the texture target. */

! Parses the incoming tape event stream to obtain the next stored byte. @param use_fast_encoding If set to @c true , inspects the tape as though

! Advances to the next block on the tape, treating it as data, then consumes, parses, and returns it. Returns @c nullptr if any wave-encoding level

! Asks the flywheel for the first synchronisation event that will occur in a given time period, indicating whether a synchronisation request occur

@returns @c true if an interrupt is currently requested; @c false otherwise.

! @returns The current scan status. */

@returns The value that a Sinclair interface would report if this joystick were plugged into it via @c port (which should be either 0 or 1, for ports

Query for implemented registers. */

@returns @c true if an entire command has been received; @c false if further bytes are needed.

An 8-bit value to rotate right @c rotate() places if @c operand2_is_immediate() is @c true; meaningless otherwise.

! Evaluates the 0th order Bessel function at @c a. */

! @returns @c true if this is an 800kb drive; @c false otherwise. */

! Evaluates to @c true if the operation actually expects a response; @c false otherwise. */

@returns @c true if this command involves reading or writing data, in which case target() will be valid. @c false otherwise.

i.e. one with the original internal timings.

@returns the total amount of time occupied by all the data stored in this segment.

@returns @c true if the lock prefix was present on this instruction; @c false otherwise.

@returns The main status register value.

@returns the name of the bit to be used as a mask for BCLR, BCHG, BSET or BTST for @c instruction given @c source.
