MEMORY_READ

#define MEMORY_READ	(		t,
			x
	)		(*(volatile uint ## t ## _t *)(x))

Read value of size t from address x.

Parameters

t	The bit count: 8, 16, or 32.
x	The byte offset.

MEMORY_WRITE

#define MEMORY_WRITE	(		t,
			x,
			y
	)

Value:

    do {                                             \
    (*(volatile uint ## t ## _t *)(x) = (y));                                  \
} while (false)

Write value y to address x of size t.

Parameters

t	The bit count: 8, 16, or 32.
x	The byte offset.
y	The value to write.

MEMORY_WRITE_AND

#define MEMORY_WRITE_AND	(		t,
			x,
			y
	)

Value:

    do {                                         \
    (*(volatile uint ## t ## _t *)(x) &= (y));                                 \
} while (false)

Bitwise AND value y to address x of size t.

Parameters

t	The bit count: 8, 16, or 32.
x	The byte offset.
y	The value to bitwise AND.

MEMORY_WRITE_OR

#define MEMORY_WRITE_OR	(		t,
			x,
			y
	)

Value:

    do {                                          \
    (*(volatile uint ## t ## _t *)(x) |= (y));                                 \
} while (false)

Bitwise OR value y to address x of size t.

Parameters

t	The bit count: 8, 16, or 32.
x	The byte offset.
y	The value to bitwise OR.
