SSR is initialized to H'84 by a reset, and in standby mode, watch mode, subactive mode, subsleep
mode, and module stop mode.
Bit 7—Transmit Data Register Empty (TDRE): Indicates that data has been transferred from
TDR to TSR and the next serial data can be written to TDR.
Bit 6—Receive Data Register Full (RDRF): Indicates that the received data is stored in RDR.
Note: RDR and the RDRF flag are not affected and retain their previous values when an error is

detected during reception or when the RE bit in SCR is cleared to 0.
If reception of the next data is completed while the RDRF flag is still set to 1, an overrun
error will occur and the receive data will be lost.

[Clearing conditions]
[Setting condition]
When serial reception ends normally and receive data is transferred from RSR to RDR
Description
When 0 is written in TDRE after reading TDRE = 1
When the DTC is activated by a TXI interrupt and writes data to TDR
When the TE bit in SCR is 0
When data is transferred from TDR to TSR and data can be written to TDR
When 0 is written in RDRF after reading RDRF = 1
When the DTC is activated by an RXI interrupt and reads data from RDR
