Notes:
31. Total power available depends on system power budget (5.4.1).
32. Each card inserted in a PCMCIA or CF slot can drain up to 1 mW when the system is in
Sleep mode ( 4 * Vcc
2
/Rpcmcia ).
33. The PCMCIA/CF voltage is software-selectable. External implementations of the CF bus
(i.e. on a Personality Board) can hard-wire the voltage to Vddx or to Vcc.
34. The SA-1110 MECR register independently sets timings for the attribute, IO and memory
spaces of the CF bus in 32 steps. Values shown assume 206 MHz CPU clock. Min values
are with Fast bit=1, max values are with Fast bit=0.
