It contains the number of bytes of a payload (including header but excluding CRC) yet to transmit: each time a data byte is written into the TXDR register, the bitfield value decrements and the TXIS bit is set, except when the bitfield value reaches zero. The enumerated values are standard payload sizes before the start of transmission."
