TIE
Transmission interrupt enable
. If it is set, each time a byte is transmitted the transmit
interrupt flag TIF is set. If it is not set, an interrupt is only generated at the end of the
frame. TIE = 0
(1)
means no interrupt after the reception of each byte. TIE = 1 means
interrupt after the reception of each byte.
Halt transmission
. This bit is set by the CPU to interrupt the transmission of the frame.
The byte currently loaded in the UART will be transmitted entirely, but the next byte will
wait until the CPU reset the bit HLTT. THLT = 0
(1)
means transmission not halted.
THLT = 1 means transmission halted.
Start transmission
. This bit is set by the CPU to start the transmission of a frame through
the UART and it is reset automatically by the queue controller at the end of transmission.
TSTF = 0
(1)
means transmission not started or ended. TSTF = 1 means transmission
started and in progress.
