15.3.7
SSR is a register containing status flags of the SCI and multiprocessor bits for transfer. 1 cannot
be written to flags TDRE, RDRF, ORER, PER, and FER; they can only be cleared. Some bit
functions of SSR differ in normal serial communication interface mode and Smart Card interface
mode.

Description
Transmit Data Register Empty
Indicates whether TDR contains transmit data.

•
Receive Data Register Full
Indicates that the received data is stored in RDR.

The RDRF flag is not affected and retains its
previous value when the RE bit in SCR is cleared
to 0. Exercise care because if reception of the next
data is completed while the RDRF flag is set to 1,
an overrun error occurs and receive data will be
lost.
When the TE bit in SCR is 0
When data is transferred from TDR to TSR, and
data writing to TDR is enabled.
When 0 is written to TDRE after reading TDRE
= 1
When the DMAC or DTC is activated by a TXI
interrupt request and transfers data to TDR
When serial reception ends normally and
receive data is transferred from RSR to RDR
When 0 is written to RDRF after reading RDRF
= 1
When the DMAC or DTC is activated by an RXI
interrupt and transferred data from RDR
