15.3.1
RSR is a shift register used to receive serial data that is 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.
15.3.2
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-enabled. Since RSR and RDR function as a double buffer in this way, enables continuous
receive operations to be performed. After confirming that the RDRF bit in SSR is set to 1, read
RDR for only once. RDR cannot be written to by the CPU.
