For Serial Communication Interface (SMIF Bit in SCMR Cleared to 0): Indicates that when
the last bit of a serial character was transmitted TDR did not contain valid transmit data, so
transmission has ended. The TEND flag is a read-only bit and cannot be written.
Bit 2
TEND
0
1
For Smart Card Interface (SMIF Bit in SCMR Set to 1): Indicates that when the last bit of a
serial character was transmitted TDR did not contain valid transmit data, so transmission has
ended. The TEND flag is a read-only bit and cannot be written.
Bit 2
TEND
0
1
Note: etu: Elementary time unit (time required to transmit one bit)
Description

The chip is reset or enters standby mode
The TE bit in SCR is cleared to 0
TDRE is 1 when the last bit of a 1-byte serial transmit character is
transmitted
The chip is reset or enters standby mode
The TE bit is cleared to 0 in SCR and the FER/ERS bit is also cleared to 0
TDRE is 1 and FER/ERS is 0 (normal transmission) 2.5 etu (when GM = 0)
or 1.0 etu (when GM = 1) after a 1-byte serial character is transmitted
