write transmit data to the serial communication data register
(SCDR). This clears the transmit data register empty (TDRE)
and transmit complete (TC) indicators in the SCSR.
vi. Enable or disable SPI interrupts (SPIE).
iii. Specify an 8- or 16-bit transfer (SIZE) and MSB- or
iv. Select master or slave operating mode (MSTR).
iii. To receive, set the receiver enable (RE) and receiver
iv. To transmit, set transmit enable (TE), transmit interrupt
v. Enable or disable wired-OR operation (WOMP).
ii. Determine use (PE) and type (PT) of parity generation

detection type (ILT) and enable or disable idle-line
interrupt (ILIE).
enable (TIE) bits in SCCR1, enable or disable wired-OR
operation (WOMC), and transmit complete interrupts
(TCIE). Disable break transmission (SBK) for normal
operation.
