serial clock, needed for command execution, is available.
this bit indicates the current state of transmitter:
No transmit repetition command is in execution.
A XREP command (register CMDRL) is currently in
execution.
No TIC (transmit immediate character) is currently in
transmission. Access to register TICR is allowed to initiate
a TIC transmission.
A TIC command (write access to register TICR) is
accepted but not completely executed. No further write
access to register TICR is allowed until ’TIC’ bit is cleared
by SEROCCO-D.
No command is currently in execution. The command
registers
A command (written previously to registers CMDRL/
CMDRH) is currently in execution. No further command
can be written to registers
Transmitter is ready (always after transmitter reset
command or XON-character detected).
Transmitter is stopped (XOFF-character detected).
