Description
Transmit Byte Count 3 to 0
These bits specify the number of data bytes to be
transmitted. The TBN value is decremented (−1) each
time one byte of FSI data transmission is completed.
When the FSI transmission ends, the TBN bits are
cleared to B'0000.
0000: Transmits no data
0001: Transmits one byte of data
0010: Transmits two bytes of data
0011: Transmits three bytes of data
0100: Transmits four bytes of data
0101: Transmits five bytes of data
0110: Transmits six bytes of data
0111: Transmits seven bytes of data
1000: Transmits eight bytes of data
1001 to 1111: Setting prohibited
If transmission of nine bytes or more is specified, data in
FSITDR7 is transmitted.
