63. unication that has taken place e Communication complete bus free e SPI timeout e Other reasons this occurs when the user tries to perform read write operations with a data length equal to zero Also there is a communication status LED available on the board It lights up whenever there is any type of communication error of type 2 or 3 above The LED status is updated after each read or write operation Depending on the CPHA and CPOL values the transfer sequence for one byte of SPI is shown in Figure 17 Therefore this interface allows any SPI interface based slave device to be connected and tested Using the UART SCI interface of the 10 pin header To use the UART1 interface it must be selected by sending the command from the DLL as mentioned in the DLL help file After this the board is ready to be used in UART1 mode The section below explains how the tool and its features behave once selection has been made using the DLLs and it also explains how the hardware setup is to be done Figure 15 below shows the interpretation of the 10 pin headers when it is configured in UART mode Figure 15 J1 interpretation for UART SCI interface J2 UART TX UART RX UART_RTS UART_CTS SCI_GPIO1 SCI GPIO2 SCL GPIO3 SCI GPIO4 AMOS832v1 Doc ID 17398 Rev 3 21 53 Running the IBU UI tool UMO935 3 3 1 3 3 2 3 3 3 22 53 Steps for making hardware connection To use any UART SCI based slave with
