transmit/receive line in half-duplex mode (open-drain configuration) if this slave is not
selected for transmission. This mode requires that slaves not selected for transmission
only shift out ones; thus, their transmit buffers must be loaded with FFFF
H
prior to any
transfer.
Note: A slave with push/pull output drivers not selected for transmission will normally
have its output drivers switched off. However, to avoid possible conflicts or
misinterpretations, it is recommended to always load the slave's transmit buffer
prior to any transfer.
The cause of an error interrupt request (receive, phase, baud rate, transmit error) can be
identified by the error status flags in control register CON.
Note: In contrast to the EIR line, the error status flags STAT.TE, STAT.RE, STAT.PE,
and STAT.BE, are not cleared automatically upon entry into the error interrupt
service routine, but must be cleared by software.
