Description
Data input and output port for the internal 64 byte FIFO-buffer. The
FIFO-buffer acts as parallel in/parallel out converter for all serial data
stream in- and outputs.
Description
Set to logic 1, this bit clears the internal FIFO-buffer’s read- and
write-pointer and the bit BufferOvfl in the register ErrReg immediately.
Reading this bit will always return 0.
Indicates the number of bytes stored in the FIFO-buffer. Writing to the
FIFODataReg increments, reading decrements the FIFOLevel.
