Single UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
7.3.2 TX
Xoff1/Xoff2 character is transmitted when the RX FIFO has passed the HALT trigger level
programmed in TCR[3:0] or the selectable trigger level in FCR[7:6]
Xon1/Xoff2 character is transmitted when the RX FIFO reaches the RESUME trigger level
programmed in TCR[7:4] or RX FIFO falls below the lower selectable trigger level in
FCR[7:6].
The transmission of Xoff/Xon(s) follows the exact same protocol as transmission of an
ordinary character from the FIFO. This means that even if the word length is set to be 5, 6,
or 7 bits, then the 5, 6, or 7 least significant bits of XOFF1/XOFF2 or XON1/XON2 will be
transmitted. (Note that the transmission of 5, 6, or 7 bits of a character is seldom done, but
this functionality is included to maintain compatibility with earlier designs.)
It is assumed that software flow control and hardware flow control will never be enabled
simultaneously. Figure 7 shows an example of software flow control.
