Data Sheet
XON
XOFF
XON Character
This bit field specifies the XON character for in-band flow control in
ASYNC protocol mode. The number of significant bits starting with the
LSB depends on the character length (5..8 bits) selected via bit field
’CHL’ in register CCR2.
A received character is recognized as a valid XON-character, if
• the character was correctly framed (character length as programmed
• each bit position of the received character which is not masked via bit
Received characters recognized as ’XON’ character are always stored
in the receive FIFO as normal receive data, but generate an appropriate
XON interrupt if enabled and switch the transmitter into ’XON’ state if in-
band flow control is enabled via bit ’FLON’ in register CCR2.
XOFF Character
This bit field specifies the XOFF character for in-band flow control in
ASYNC protocol mode. The number of significant bits starting with the
LSB depends on the character length (5..8 bits) selected via bit field
’CHL’ in register CCR2.
A received character is recognized as a valid XOFF-character, if
• the character was correctly framed (character length as programmed
• each bit position of the received character which is not masked via bit
Received characters recognized as ’XOFF’ character are always stored
in the receive FIFO as normal receive data, but generate an appropriate
XOFF interrupt if enabled and switch the transmitter into ’XOFF’ state if
in-band flow control is enabled via bit ’FLON’ in register CCR2.
