26.3.3
SSITDR is a 32-bit register that stores data to be transmitted.
Data written to SSITDR is transferred to the shift register as it is required for transmission. If the
data word length is less than 32 bits then its alignment should be as defined by the PDTA control
bit in SSICR.
Reading this register will return the data in the buffer.
26.3.4
SSIRDR is a 32-bit register that stores the received data.
Data in SSIRDR is transferred from the shift register as each data word is received. If the data
word length is less than 32 bits then its alignment should be as defined by the PDTA control bit in
SSICR.
