2nd UART on at89c51re2

Hello!

I have problem with configuration of UART_1 on at89c51re2 micro controller I supposed that is because I am using a at89c51xd2.h header file which does not include definition for UART_1. When I try to define
Sbit (ES1 , 0xB1, 3);
in IEN1 (0xB1) register i receive error message error C142: 'SFR': invalid base address.

Any help?

Thanks in advance

1. I made error when I had selected C251, it should be C51.
If 2.) is in relationship with 1.) I think that now you understand that is not a problem because I selected MCU Architecture C251 when posted message.
