Serial Control Direction 1
In Synchronous mode (SYN = 1) when transmitter 2 is disabled (TE2 = 0),
or in Asynchronous mode (SYN = 0), SCD1 controls the direction of the
SC1 I/O signal. When SCD1 is set, SC1 is an output; when SCD1 is
cleared, SC1 is an input. When TE2 is set, the value of SCD1 is ignored
and the SC1 signal is always an output.
Serial Control Direction 0
In Synchronous mode (SYN = 1) when transmitter 1 is disabled (TE1 = 0),
or in Asynchronous mode (SYN = 0), SCD0 controls the direction of the
SC0 I/O signal. When SCD0 is set, SC0 is an output; when SCD0 is
cleared, SC0 is an input. When TE1 is set, the value of SCD0 is ignored
and the SC0 signal is always an output.
Serial Output Flag 1
In Synchronous mode (SYN = 1), when transmitter 2 is disabled (TE2 = 0),
the SC1 signal is configured as ESSI flag 1. When SCD1 is set, SC1 is an
output. Data present in bit OF1 is written to SC1 at the beginning of the
frame in Normal mode or at the beginning of the next time slot in Network
mode.
Serial Output Flag 0
In Synchronous mode (SYN = 1), when transmitter 1 is disabled (TE1 = 0),
the SC0 signal is configured as ESSI flag 0. When SCD0 is set, the SC0
signal is an output. Data present in Bit OF0 is written to SC0 at the
beginning of the frame in Normal mode or at the beginning of the next time
slot in Network mode.
