Byte Index
It indicates which data byte in transmit data shift register. When all data in FIFO is
transmitted and it will be cleared to 0.
It is a read only bit.
TX FIFO Empty
When S/W writes any data to PS2TXDATA0-3 the TXEMPTY bit is cleared to 0
immediately if PS2EN is enabled. When transmitted data byte number is equal to
FIFODEPTH then TXEMPTY bit is set to 1.
1 = FIFO is empty
0 = There is data to be transmitted
Read only bit.
RX Buffer Overwrite
1 = Data in PS2RXDATA register is overwritten by new received data
