#102318 - TL16C754 software flow control question Responding to: ???'s previous message |
I want to use DMA1 mode and software flow control as the example described at the datasheet.But i found the transmission
mode is DMA0.that is to say,once i transmit a character,the receive uart will enter into interrupt.But when uart1 send characters up to the number set by TLR[7:4],uart2 can't enter interrupt. help! |

what does that have to do with bit-bangi | 01/01/70 00:00 | |
| nope, there are many external UARTs ava | 01/01/70 00:00 |
