INC_512 (512 Increment)
0 A INC_512 bit set to zero specifies that the TRANSFER LENGTH field indicates the number of bytes to be transferred.
1 INC_512 bit set to one specifies that the TRANSFER LENGTH field (see 2.2.4) expresses the number of bytes to be transferred in incre-
ments of 512 bytes (e.g., a value of one means 512 bytes, two means 1,024 bytes, etc.). Pad bytes shall be appended as needed to meet
this requirement. Pad bytes shall have a value of 00h.
Any association between a SECURITY PROTOCOL OUT command and a subsequent SECURITY PROTOCOL IN command depends
on the protocol specified by the SECURITY PROTOCOL field (see table 184). Each protocol shall define whether:
a) The device server shall complete the command with GOOD status as soon as it determines the data has been correctly received. An indi-
cation that the dat has been processed is obtained by sending a SECURITY PROTOCOL IN command and receiving the results in the
associated data transfer; or
b) The device server shall complete the command with GOOD status only after the data has been successfully processed and an associated
SECURITY PROTOCOL IN command is not required.
The format of the data transferred depends on the protocol specified by the SECURITY PROTOCOL field (see table 184).
