RX_ASCII_CODE
PS2 Host Controller Received Data Filed
This field stores the ASCII data content transmitted from device.
Therefore, this part translates the scan code into an ASCII
value. It will be read as 0x2E when there is no ASCII code
mapped to the scan code stored in RX_SCAN_CODE register.
This filed is valid when RX_IRQ is asserted.
