SERDAT[7: 0]: PS/2 mouse data input port. This port is a 2 bytes FIFO. Therefore, about 1 mini-second delay is

allowed between RXFLG in SERCTL register set and to read the PS/2 mouse data. If the 2 bytes FIFO full,

GL602USB will drive the PS/2 clock low to avoid the mouse send more data.

Value on POR: “X X X X X X X X”
