The CTS pin, if enabled by the CTSE bit of the UART Control 0 register, performs flow
control on the outgoing transmit datastream. The Clear To Send (CTS) input pin is
sampled one system clock before beginning any new character transmission. To delay
transmission of the next data character, an external receiver must deassert CTS at least one
system clock cycle before a new data transmission begins. For multiple character trans-
missions, this action is typically performed during Stop Bit transmission. If CTS deasserts
in the middle of a character transmission, the current character is sent completely.
The UART has a MULTIPROCESSOR (9-bit) mode that uses an extra (9
selective communication when a number of processors share a common UART bus. In
MULTIPROCESSOR mode (also referred to as 9-bit mode), the multiprocessor bit (

Multiprocessor control bit. The UART Control 1 and Status 1 registers provide
MULTIPROCESSOR (9-bit) mode control and status information. If an automatic address
matching scheme is enabled, the UART Address Compare register holds the network
address of the device.
MULTIPROCESSOR (9-bit) Mode Receive Interrupts
When MULTIPROCESSOR mode is enabled, the UART only processes frames addressed
to it. The determination of whether a frame of data is addressed to the UART can be made
