Lower values make the TIMESTAMP
more precise when the EXTENDED
MODE is used and minimizes the
overrun errors. However, values too
low may cause too many interruptions
and delay the CPU.
When true, select the RX line and the
block extended mode.
SERIAL_RX_EXTENDED must be
used to receive data. On the other
hand, for the RX line with normal
format, the SERIAL_RX block must be
used to receive data.
When true, all the received byte during
the transmission will be discharged
instead going to the RX line. Used to
disable the full-duplex operation in the
RS-422 interface.
When true, generates an external
event when the DCD is modified.
When true, generates an external
event when the CTS is modified.
List all parity possibilities.
List all available serial ports (COM 10,
COM 11, COM 12, COM 13, COM 14,
COM 15, COM 16, COM 17, COM 18,
and COM 19 – expansion modules).
Defines a character in the RX queue in extended mode.
Silence due to the previous character
or due to another event which has
happen before this character (serial
port configuration, transmission
ending).
It has some fields which deliver information regarding RX queue
status/error, used when the normal format is utilized (no error and
timestamp information):
Frame errors counter: character
incorrect formation – no stop bit,
incorrect baud rate, among other –
since the serial port configuration.
Returns to zero when it reaches the
maximum value (65535).
Parity errors counter, since the serial
port configuration. Returns to zero
when it reaches the maximum value
(65535).
Interruption errors counter, since the
serial port configuration, in other
words, active line higher than the
character time. Returns to zero when it
reaches the maximum value (65535).
FIFO RX overrun errors counter, since
the serial port configuration, in other
words, error in the FIFO RX configured
threshold. Returns to zero when it
reaches the maximum value (65535).
RX queue overrun errors counter, in
other words, the maximum characters
number (1024) was overflowed and the
