When the TE bit in SCR is 0
When data is transferred from TDR to TSR
When 0 is written to TDRE after reading TDRE = 1
(When the CPU is used to clear this flag by writing 0
while the corresponding interrupt is enabled, be sure
to read the flag after writing 0 to it.)
When a TXI interrupt request is issued allowing
DMAC or DTC to write data to TDR
