Hello Peter Herbst,

I am interfacing CF with 16F73 PIC controller in LBA mode. I am able to write/read a single sector. When i am trying to read more sectors i am getting DATA only from two sectors and further reads result zero DATA.

I am interfacing the following pins only

DATA pins - D1,D2,D3,D4,D5,D6,D7

Address pins - A2,A1,A0

other address pins and CSEL are grounded

Control pins - WE,RDY/BSY,RESET

REG,CE2 are connected to Vcc.

other pins are left open.

One more thing with this interface i am not able to use CHS mode.

Thanks and regards,
Venkat.
