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.
