Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR
There are two other enhanced features relating to software flow control:
Xon Any function (MCR[5]): Receiving any character will resume operation after
recognizing the Xoff character. It is possible that an Xon1 character is recognized as
an Xon Any character, which could cause an Xon2 character to be written to the
RX FIFO.
Special character (EFR[5]): Incoming data is compared to Xoff2. Detection of the
special character sets the Xoff interrupt (IIR[4]) but does not halt transmission. The
Xoff interrupt is cleared by a read of the Interrupt Identification Register (IIR). The
special character is transferred to the RX FIFO.
7.3.1 Receive flow control
When software flow control operation is enabled, the SC16IS752/SC16IS762 will
compare incoming data with Xoff1/Xoff2 programmed characters (in certain cases, Xoff1
and Xoff2 must be received sequentially). When the correct Xoff characters are received,
transmission is halted after completing transmission of the current character. Xoff
detection also sets IIR[4] (if enabled via IER[5]) and causes IRQ to go LOW.
To resume transmission, an Xon1/Xon2 character must be received (in certain cases
Xon1 and Xon2 must be received sequentially). When the correct Xon characters are
received, IIR[4] is cleared, and the Xoff interrupt disappears.
7.3.2 Transmit flow control
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/Xon2 character is transmitted when the RX FIFO reaches the resume trigger level
programmed in TCR[7:4], or 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, 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.
