Hi, i am developing an application which implements the keil another Asynchronous port. Here we are using keil ST10168 board. we are having the 8251 as the USART. To connect 8251 with the board,we have taken the 8 bit demultiplexed bus. Can you please tell me how to set the chip select and others fields. How i can know the chip select is connected to my USART. Thanks & Regards Bharathi M.
Hi, Thank you for your reply. But while configuring the board we are trying to change the SYSCON some variable in the start167.a166 file. eventhough the values are not reflecting. can any one you give the reason why it is happening like that. Actually i wanted change the default settings of the CSSEL and SALSEL.we have changed the CSSEL in the dip switches and RSTCON register. But when i am changing the DIP of SALSEL value then Monitor error is coming. so, i have changed in the RSTCON register with the help of SUE bit setting in that register. Even thought the Regiser values of RP0H are not reflecting. Could any one give reason why it is behaving like that. Regards Bharathi
