If set no LPCD IRQ is raised any more until the next low-power
card detection procedure. Can be used by software to clear the
interrupt source

Description
Enables the output functionality on SIGIN (pin 5). The pin is then used
as I/O then.
Enables the output functionality of the CLKOUT (pin 22). The pin is
then used as I/O then. The CLKOUT function is switched off
Enables the output functionality of the IFSEL1 (pin 27). The pin is then
used as I/O then.
Enables the output functionality of the IFSEL0 (pin 26). The pin is then
used as I/O then.
Enables the output functionality of the TCK (pin 4) of the boundary
scan interface. The pin is then used as I/O. If the boundary scan is
activated in EEPROM, this bit has no function.
Enables the output functionality of the TDI (pin 2) of the boundary scan
interface. The pin is then used as I/O. If the boundary scan is activated
in EEPROM, this bit has no function.
Enables the output functionality of the TDO (pin 1) of the boundary
scan interface. The pin is then used as I/O. If the boundary scan is
activated in EEPROM, this bit has no function.
Enables the output functionality of the TMS (pin 3) of the boundary
scan interface. The pin is then used as I/O. If the boundary scan is
activated in EEPROM, this bit has no function.
