MS08 DZ60 SCI Signal-Wire Operation

Discussion created by qiong yu on Oct 12, 2016

Hi,

When i use the Signal-Wire mode of the SCI on the chip of MS08DZ60, I met a problem. When i send some bytes vai the TXD pin, the SCI will occur trannsmit complete interrupt, but the receive buffer full interrupt is not occurs. In the datasheet, it says when In single-wire mode, the internal loop back connection from the transmitter to the receiver causes the receiver to receive characters that are sent out by the transmitter. So the transmitter is connect to the receiver, why no receive interrupt occurs?
