Note Deadlocks can occur i f one SC I Transmit block tries
to communicate with more than one SCI Receive block on
different COM po rts when both are blocking (using protocol
mode). Deadlocks cannot occur on the same COM port.
Data byte order
Select
Little Endian or Big Endian.
Data swap width
Select
8-bits or 16-bits.
Enable Loopback
Select this to enab le th e lo op ba ck f u nction f or sel f-t est an d
diagnostic purposes only. When this function is enabled, the
Tx pin on a C28x DSP is internally connected to its Rx pin
and can transmit data from its output port to its input port
to check the integrity of the transmission.
Number of stop bits
Select whether to use
1 or 2 stop bits.
Parity mode
Type of parity to use. Available selections are
None, Odd
parity, or Even parity. None disables parity. Odd sets the
parity bit to one if you have an odd number of ones in your
bytes, such as 00110010.
Even sets the parity bit to one if
you have an even number of ones in your b ytes, such as
00110011.
Rx pin assignment
Assigns the SCI receive something to a GPIO pin. Choices
are
None (default), GPI011, GPI015, GPI019,orGPI023.
Tx pin assignment
Assigns the SC I transmit something to a GPIO pin. Choices
are
None (default), GPI09, GPI014, GPI018,orGPI022.
