Bit 6—Transmit End (TEND): Indicates that there is no valid data in SCFTDR when the last bit of
the transmit character is sent, and transmission has been ended.
Bit 6: TEND
Description
0
Transmission is in progress
[Clearing condition]
When data is written to SCFTDR while TE = 1
1
Transmission has been ended
(Initial value)
[Setting conditions]
•
In a reset or in standby mode
•
When the TE bit in SCSCR is 0
•
When there is no transmit data in SCFTDR on transmission of the last bit of
a 1-byte serial transmit character
Bit 5—Transmit Data FIFO Empty (TDFE): Indicates that data has been transferred from the
transmit FIFO data register (SCFTDR) to the transmit shift register (SCTSR), the number of data
bytes in SCFTDR has fallen to or below the transmit trigger data number set by bits TTRG1 and
TTRG0 in the FIFO control register (SCFCR), and transmit data can be written to SCFTDR.
Bit 5: TDFE
Description
0
A number of transmit data bytes exceeding the transmit trigger set number
have been written to SCFTDR
[Clearing conditions]
•
When transmit data exceeding the transmit trigger set number is written to
SCFTDR, and 0 is written to TDFE after reading TDFE = 1
•
When transmit data exceeding the transmit trigger set number is written to
SCFTDR by the on-chip DMAC
1
The number of transmit data bytes in SCFTDR does not exceed the transmit
trigger set number
(Initial value)
[Setting conditions]
•
In a reset or in standby mode
•
When the number of SCFTDR transmit data bytes falls to or below the
transmit trigger set number as the result of a transmit operation
*
Note:
*
As SCFTDR is a 16-byte FIFO register, the maximum number of bytes that can be written
when TDFE = 0 is {16 – (transmit trigger set number)}. Data written in excess of this will be
ignored. The number of data bytes in SCFTDR is indicated by the upper 8 bits of SCFDR.
