13.3.1
RSR is a shift register that is used to receive serial data input to the RxD pin and convert it into
parallel data. When one byte of data has been received, it is transferred to RDR automatically.
RSR cannot be directly accessed by the CPU.
13.3.2
RDR is an 8-bit register that stores receive data. When the SCI has received one byte of serial
data, it transfers the received serial data from RSR to RDR, where it is stored. After this, RSR is
Receive Shift Register (RSR)
