Personal System 2 Block
The Nuvoton Keyboard controller has three independent PS/2 serial ports implemented in hardware,
which are directly controlled by the on chip 8051. Each of the three PS/2 serial channels uses a
synchronous serial protocol to communicate with the auxiliary device. Each PS/2 channel has two
signal lines: Clock and Data. Both signal lines are bi-directional and employ open drain. The
PS2DATA, PS2CON and PS2STS is defined individually for each PS/2 channel. PS2HSEN is only
one register for controlling all PS/2 device handshake action.

6.3.1
Register Description
6.3.1.1
PS/2 Handshake Enable Register (PS2HSEN) (Default Value:: 0000_0000)
Bit 7~1: Reserved (always return ‘LOW’)
Bit 0: Handshake Mode Enable (HSEN)
0: The handshake mode of PS2 disables.
1: The handshake mode of PS2 enables.
When the handshake mode of PS2 is enabling, the TR bit (BIT 0) of PSCON is automatically set high
when the START_DEC bit (bit 6) of PS2STS of the other channel is set.
Note:
The priority of three PS2 interface is KPS2 > MPS2 > APS2.
Whether the handshake mode of PS2 is enabled or not, the TR bit (BIT 0) of PSCON is
automatically set high when the RDATA_RDY bit (bit 0) of PS2STS of this channel is set.
