Shifter Status Flag
The shifter status flag is updated when one of the following events occurs:
For SMOD=Receive, the status flag is set when SHIFTBUF has been loaded with data from Shifter
(SHIFTBUF is full), and the status flag is cleared when SHIFTBUF register is read.
For SMOD=Transmit, the status flag is set when SHIFTBUF data has been transferred to the Shifter
(SHIFTBUF is empty) or when initially configured for SMOD=Transmit, and the status flag is cleared
when the SHIFTBUF register is written.
For SMOD=Match Store, the status flag is set when a match has occured between SHIFTBUF and
Shifter, and the status flag is cleared when the SHIFTBUF register is read.
For SMOD=Match Continuous, returns the current match result between the SHIFTBUF and Shifter.
For SMOD=State, the status flag for a shifter will set when it is selected by the current state pointer.
For SMOD=Logic, returns the current value of the programmable logic block output.
