UARTC Power Down. 0: Powered down 1: Not powered down
IPD (Immediate Power Down). When set to 1, the whole chip is put into
power-down mode immediately.
CLKSEL => Input clock rate selection
= 0 The clock input on pin 18 is 24 MHz.
= 1 The clock input on pin 18 is 48 MHz. (Default)
Select output type of SYSFANOUT
=0 SYSFANOUT is Open-drain. (Default)
=1 SYSFANOUT is Push-pull.
Select output type of CPUFANOUT0
=0 CPUFANOUT is Open-drain. (Default)
=1 CPUFANOUT is Push-pull.
ENKBC => Enable keyboard controller
= 0 KBC is disabled after hardware reset.
= 1 KBC is enabled after hardware reset.
This bit is read-only, and it is set or reset by a power-on strapping pin (Pin
54, SOUTA).
ENFDC => Enable FDC interface
= 0 FDC is enabled after hardware reset.
= 1 FDC is disabled after hardware reset.
This bit is set or reset by a power-on strapping pin (Pin 52, DTRA#).
