Bit 7 6 5 4 3 2 1 0
Bytes 2..11 PIN KSN. If fixed PIN key is used, KSN is zero.
Bytes 12..19 Encrypted PIN block
3.5.6 Report 0x25 – User Selection Response Report
This event is triggered when the user is asked to choose an account type, which causes the device to send
the user’s response (i.e. the key pressed) to the host.

Bit 7 6 5 4 3 2 1 0
Byte 0 0x25
Byte 1 Operation Status (see Appendix C Status and Message Table)
Byte 2 Code of key pressed:
0x71 = left function key
0x72 = middle function key
0x74 = right function key
0x78 = ENTER key
3.5.7 Report 0x27 – Display Message Done Report
This event is sent by the device to the host to indicate a pending Report 0x07 – Display Message has
completed.

Byte 0 0x27
Byte 1 Operation Status
3.5.8 Report 0x29 – Send Big Block Data to Host
This event is used by the device to send the user’s signature, device certificate, or CSR to the host. If the
data size is greater than 123 bytes, the data must be broken into multiple 123-byte data blocks, or packets.
Three data formats are used in connection with this command:

The first packet (block 0) is used to signal the start of sending, which defines the buffer type, buffer
status, and the total length of data being sent (in bytes);

Subsequent packets (blocks 1 through n) contain the requested data; and

A final packet signifies the end of sending.
If the big buffer type is SECURED or MAC, the first 2 bytes of the data packet are the expected data
length after decryption.
