Non-data None Number Get slot number. Register Sector Number will response how many slot is
of slots supported.
Non-data None Media Check media connection. Error register response media status.
status Definition of error register:
if bit 1 is true, and
if bit 4 is true. no media insert, else (false) media is insert
if bit 5 is true, media write protect, else (false) media write enable
if bit 6 is true, media initial failed, else (false) media initial pass
if bit 7 is true, same with bit 4
if bit 1 is false, and
if bit 5 is true, media change, (memory card already been change,
need to initial command 0x62)
Non-data None None Initialize Media. After power on or media change, Initial media command
must be executed.
PIO data None 512 Read Serial Number(16bytes), VID and PID. It is some control flow with
in
Bytes of command 0xEC. 512 bytes will be sent out as follows,
S/N, Byte Description
VID and 0
Valid serial number length
PID _{1 ~ 24 Serial Number (valid data is according length)}
25
VID (Low Byte)
26
VID(High Byte)
27
PID(Low Byte)
28
PID(High Byte)
Non-data None None When this command is accessed, it will go to suspend mode and force pin
ACT_nSPND low. When next IDE command access, it will auto wake up
and force pin ACT_nSPND high.
