Macro imxrt_dcd::clear_reg

macro_rules! clear_reg {
    ($periph:path, $instance:ident, $reg:ident $([$offset:expr])*, $($args:tt)+) => { ... };
}

Creates a DCD command that clears specified bits / fields to 0 in the specified RAL register, i.e. register &= !(arg1 | arg2 | ...) .

Syntax:

write_reg!(ral::path::to::peripheral, INSTANCE, REGISTER, ...args)

Each arg can be FIELD: value, @FIELD (= all bits of the field), or an arbitrary expression. All args are bitwise-OR’d together to form the final value. See crate-level docs for details on args.

Returns a crate::Command::Write with crate::WriteOp::Clear.

Example

dcd::clear_reg!(ral::ccm, CCM, CBCMR, @PERIPH_CLK2_SEL)
