These bits select the mode of operation of the USART as shown in
“USART Control and Status Register n C – UCSRnC” on page 215
the normal USART operation. The MSPIM is enabled when both UMSELn bits are set to
one. The UDORDn, UCPHAn, and UCPOLn can be set in the same write operation where
the MSPIM is enabled.
When in MSPI mode, these bits are reserved for future use. For compatibility with future
devices, these bits must be written to zero when UCSRnC is written.
When set to one the LSB of the data word is transmitted first. When set to zero the MSB of
the data word is transmitted first. Refer to the section
details.
The UCPHAn bit setting determine if data is sampled on the leasing edge (first) or tailing
(last) edge of XCKn. Refer to the section
details.
The UCPOLn bit sets the polarity of the XCKn clock. The combination of the UCPOLn and
UCPHAn bit settings determine the timing of the data transfer. Refer to the section
Data Modes and Timing” on page 221
