Module kernel::common::regs

Implementation of registers and bitfields.

Allows register maps to be specified like this:

use common::regs::{ReadOnly, ReadWrite, WriteOnly};

#[repr(C)]
struct Registers {
    // Control register: read-write
    cr: ReadWrite<u32, Control::Register>,
    // Status register: read-only
    s: ReadOnly<u32, Status::Register>,
}

and register fields and definitions to look like:

register_bitfields![u32,
    Status [
        TXCOMPLETE  OFFSET(0) NUMBITS(1) [],
        TXINTERRUPT OFFSET(1) NUMBITS(1) [],
        RXCOMPLETE  OFFSET(2) NUMBITS(1) [],
        RXINTERRUPT OFFSET(3) NUMBITS(1) [],
        MODE        OFFSET(4) NUMBITS(3) [
            FullDuplex = 0,
            HalfDuplex = 1,
        Loopback = 2,
            Disabled = 3
        ],
        ERRORCOUNT OFFSET(6) NUMBITS(3) []
    ]
];
