TIC Executing
This status bit indicates that transmission instruction of currently
programmed TIC (Transmit Immediate Character) is accepted but not
completely executed. Further access to register TIC is only allowed after
STAR.TEC has been reset by the ESCC8.
Note: Status flag TEC is set immediately with the write access to register
TIC. It remains active until the transmitter of ESCC8 is able to start
transmission of currently programmed TIC. Best case: TEC remains
set for at most 2.5 clock periods (transmit clock or master clock,
depending of the selected mode) if transmission of the programmed
TIC character can be started immediately.
The function of register TIC and status flag TEC is independent of
whether flow control is enabled or not.
Command Executing
0… no command is currently being executed, the CMDR register can be
written to.
1… a command (written previously to CMDR) is currently being executed,
no further command can be temporarily written in CMDR register.
Note: CEC will be active at most 2.5 transmit clock periods. If the ESCC8
is in power down mode CEC will stay active.
Clear To Send State
This bit indicates the state of the CTS pin.
0… CTS is inactive (high)
1… CTS is active (low)
