PS/2 Keyboard Key Data Registers (PS2KEY0 - PS2KEY7)

Eight registers (PS2KEY0-PS2KEY7) store the scan codes for the password or key sequence of the keyboard wake-up fea-

ture, as follows:

PS2KEY0 register stores the scan code for the ﬁrst key in the password/key sequence.

PS2KEY1 register stores the scan code for the second key in the password/key sequence.

PS2KEY2 - PS2KEY7 registers store the scan codes for the third to eighth keys in the password/key sequence.

When one of these registers is set to 00h, it indicates that the value of the corresponding scan code byte is ignored (not

compared). These registers are set to 00h on power-up of VPP or software reset.
