Is it value or address?

Jani Jani

We use NXP LPC2468 Microcontroller in our target board.

We use Keil tools to build and debug our embedded C++ application.

#define UART1_BASE_ADDR         0xE0010000
#define U1RBR          (*(volatile unsigned long *)(UART1_BASE_ADDR + 0x00))

What is contents of U1RBR ?

Is it address 0xE0010000 ?

or

Is it the value stored at address 0xE0010000.

Thank you!
