Function mcrr 

pub unsafe fn mcrr<const CP: u32, const OP1: u32, const CRM: u32>(
    a: u32,
    b: u32,
)

This instruction moves two Registers to Coprocessor Registers.

This function generates inline assembly and needs the instruction configuration during compilation time (i.e. as const).

The values of the constants required by this function should be defined by the coprocessor’s reference manual.

• CP: The coprocessor’s index.
• OP1: First optional operation for the coprocessor.
• CRM: Coprocessor register M.
