Hi all,


I used Beekit MAC codebase for MC13224,

I don't know why UART TX is not generate interrupt in *case.


case 1: I write by function  UartWriteData(UART_1, "P", 1); interrupt generated

*case 2: I write by direct register UART1.Udata = 'P'; interrupt not generatep


I would like to write at direct uart register(UART1.Udata), when FIFO empty then generate Interupt Tx


Please knowledge to solv for me.
