9. CF Controller
9.1. CFCON feature
CF Controller support only True-IDE mode.(don’t support PC card mode.) This is compatible with ATA/ATAPI-6
standard.
Cautions
(1) Check voltage domain of CF address and data, because addr/data shared MSM interface.
(2) CF Card Vdd is controlled by GPIO. Because CF Controller don’t support Hot-plug function. So if your B’d
turn-on state and CF card inserted after, CF controller don’t recognize. So you have to control the Vdd by
GPIO (turn-off and a few time after turn-on)
