18.3.3 Transmit Data Register (SSITDR)
SSITDR is a 32-bit register that stores data to be transmitted.
Data written to this register is transferred to the shift register upon transmission request. If the data
word length is less than 32 bits, the alignment is determined by the setting of the PDTA control bit
in SSICR. The data in the buffer can be accessed by reading this register.

18.3.4 Receive Data Register (SSIRDR)
SSIRDR is a 32-bit register that stores receive messages.
Data in this register is transferred from the shift register each time data word is received. If the
data word length is less than 32 bits, the alignment is determined by the setting of the PDTA
control bit in SSICR.
