Symbol

available

If this bit is set the mini UART receive FIFO contains

at least 1 symbol

If this bit is clear the mini UART receiver FIFO is

empty

R 0

Receiver is idle

This bit is only useful if the receiver is disabled. The normal use is to disable the receiver.

Then check (or wait) until the bit is set. Now you can be sure that no new symbols will

arrive. (e.g. now you can change the baudrate...)

Transmitter is idle

This bit tells if the transmitter is idle. Note that the bit will set only for a short time if the

transmit FIFO contains data. Normally you want to use bit 9: Transmitter done.

RTS status

This bit is useful only in receive Auto flow-control mode as it shows the status of the RTS

line.

This is the same register as is accessed using the LABD bit and the first two register, but

much easier to access.
