Full-duplex communication capability
Choice of LSB-first or MSB-first transfer
On-chip baud rate generator allows any bit rate to be selected
Choice of serial clock source: internal clock from baud rate generator or external clock from
SCK pin
Four interrupt sources
Module stop mode can be set
Receive error detection : Overrun errors detected
The transmitter and receiver are mutually independent, enabling transmission and reception
Double-buffering is used in both the transmitter and the receiver, enabling continuous
