19.3.1
RSR is a shift register which is used to receive serial data input from the RxD pin and converts it
into parallel data. When one frame of data has been received, it is transferred to RDR
automatically. RSR cannot be directly accessed by the CPU.
19.3.2
RDR is an 8-bit register that stores receive data. When the SCI has received one frame of serial
data, it transfers the received serial data from RSR to RDR where it is stored. This allows RSR to
receive the next data. Since RSR and RDR function as a double buffer in this way, continuous
receive operations can be performed. After confirming that the RDRF bit in SSR is set to 1, read
RDR only once. RDR cannot be written to by the CPU.
