serial clock, needed for command execution, is available.
Optionally this input can be programmed to generate an interrupt
on signal level changes.
No transmit repetition command is in execution.
A XREP command (register CMDRL) is currently in
execution.
No command is currently in execution. The command

A command (written previously to registers CMDRL/
CMDRH) is currently in execution. No further command
can be written to registers
Less than or equal to 32 bytes have been written to the
XFIFO.
More than 32 bytes have been written to the XFIFO. This
bit is reset by:
– a transmitter reset command ’XRES’
– or when all bytes in the accessible half of the XFIFO
The XFIFO is not able to accept further transmit data.
Transmit data can be written to the XFIFO.
CTS input signal is inactive (high level)
CTS input signal is active (low level)
