0: 12 bit Address Qualification
1: 16 bit Address Qualification
CLKSEL
0: The clock input on Pin 1 should be 24 Mhz.
1: The clock input on Pin 1 should be 48 Mhz.
The corresponding power-on setting pin is SOUTB (pin 83).
Reserved
ENKBC(Read Only)
0: KBC is disabled after hardware reset.
1: KBC is enabled after hardware reset.
This bit is set/reset by power-on setting pin SOUTA(pin 54).
Reserved
PNPCVS
0: The Compatible PnP address select registers have default values.
1: The Compatible PnP address select registers have no default value.
When trying to make a change to this bit, new value of PNPCVS must be complemen-
tary to the old one to make an effective change. For example, the user must set
PNPCVS to 0 first and then reset it to 1 to reset these PnP registers if the present value
of PNPCVS is 1. The corresponding power-on setting pin is NDTRA (pin 52).
Reserved
URBTRI. UART2 output pin tri-stated.
URATRI. UART1 output pin tri-stated.
PRTTRI. Parallel port output pin tri-stated.
Reserved
FDCTRI. FDC output pin tri-stated.
IPD (Immediate Power Down). When set to 1, it will put the whole chip into power
down mode immediately.
Reserved.
