13.2
13.2.1
RSR is the register that receives serial data.
The SCI loads serial data input at the RxD pin into RSR in the order received, LSB (bit 0) first,
thereby converting the data to parallel data. When 1 byte has been received, it is automatically
transferred to RDR. The CPU cannot read or write RSR directly.
13.2.2
RDR is the register that stores received serial data.
When the SCI finishes receiving 1 byte of serial data, it transfers the received data from RSR into
RDR for storage. RSR is then ready to receive the next data. This double buffering allows data to
be received continuously.
RDR is a read-only register. Its contents cannot be modified by the CPU. RDR is initialized to
H'00 by a reset and in standby mode.
